AMSAT-DL Proposes Next Generation GEO/MEO Amateur Radio Payload

At the request of the IARU, the European Space Agency (ESA) is supporting an initiative to define a future amateur radio satellite payload in geostationary orbit. The implementation is to take place through collaborative cooperation between internal, industrial and amateur radio participants. This activity will consolidate the requirements of the amateur and commercial satellite industry, weigh up different payload options, address the future user segment, develop scenarios for the financing, procurement and operation of such a payload, and investigate possibilities for placement on geostationary platforms.

This past weekend, AMSAT-DL released their proposal. AMSAT-UK, along with the British Amateur Television Club, AMSAT-NA, and the UK Microwave Group previously made a separate proposal. AMSAT-DL’s proposal is written by the authors Kai Siebels, DH0SK and Matthias Bopp, DD1US. The proposal takes into account the technical requirements and needs of radio amateurs. Various aspects such as orbit, satellite and platform as well as payload are taken into account.

Among the possible orbits such as MEO, HEO and GEO, the GEO orbit has proven to be the most suitable due to the extensive experience with OSCAR-100. A good compromise for the orbit position would be at ~43 degrees West to also support Eastern European countries and most of North America.

A payload for amateur radio should allow the greatest possible scope for experiments on different bands. Six bands could be used for the uplink to enable experiments with different frequencies. The main uplink band is the 13 cm band, the main downlink band is the 3 cm band. All proposed band / NB transponder combinations can be implemented at the ground station with very reasonable effort.

A dedicated AMSAT (Amateur Radio) mission based on an ESA-supported Micro GEO provides opportunities for several additional experiments that support AMSAT’s education, science and development goals to inspire young people with amateur radio technology. Finally, such a mission could also provide an excellent platform for disaster/emergency communications directly via the GEO satellite transponders.

Micro GEO and QO-100

Micro GEO satellites are a new class of small geostationary communications satellites. They are around a tenth of the size of traditional geostationary satellites and typically measure just one cubic meter. This smaller size makes them significantly cheaper to manufacture and launch, allowing satellite operators to offer customized regional services or gap fillers that would not be financially feasible with large satellites.

The amateur radio payload “QO-100” on the Es’hail-2 geostationary satellite, is a groundbreaking platform for the amateur radio community as it represents the first geostationary payload for amateur radio. The exemplary collaboration between AMSAT-DL, QARS and commercial partners on this project to integrate amateur radio payloads into a commercial satellite is a sign of the ongoing cooperation between the amateur radio community and the commercial space industry. This synergy can open up new avenues for amateur radio projects in space. QO-100 serves as a bridge between traditional approaches and new possibilities, while remaining firmly rooted in the principles of amateur radio. Its presence in geostationary orbit is a triumph for the amateur radio community and a sign that amateur radio can continue to play an important role in the exploration and use of space.

SYNCART 2.0 on the Heinrich Hertz satellite

The Heinrich Hertz Satellite Mission (also known as H2Sat) is a national, geostationary communications and research satellite. It was planned by the Space Agency of the German Aerospace Center (DLR) on behalf of the BMWi as part of the German government’s space strategy and serves both independent payloads (“hosted payloads”) and the in-orbit verification (IOV) of technologies as well as for research purposes.

In July 2012, AMSAT-Germany (AMSAT-DL) proposed an amateur radio payload on the Heinrich Hertz satellite with the name “SYNCART 2.0”. This was a further development of the transponders of the P3-D AMSAT-OSCAR-40 satellite in the X and K amateur radio bands and a beacon in the 76 GHz band.

The objectives of the amateur radio payload were as follows:

  • Development of the geostationary orbit for the amateur radio service
  • Communication resource for emergency and disaster radio (with low-power, small, simple technology)
  • In-orbit verification of SDX technologies
  • Promoting the spread of microwave technology
  • Gaining new insights by studying propagation conditions in the 76 GHz band for satellite applications
  • Provision of a signal for the calibration of antennas, converters and receivers, in particular for radio astronomical applications
  • Stimulating the acquisition of scientific and technical education, especially among schoolchildren and young people, by providing a permanently available satellite resource, e.g. for use in teaching, research and education
  • Acquisition of concrete knowledge and experience with satellite technologies and corresponding research opportunities in order to provide the space industry with highly qualified specialists.

The concept aimed to make efficient and effective use of any remaining H2Sat capacity.

The Heinrich Hertz feasibility study was completed in 2010. Planning phase B was carried out from 2011 to 2013. In July 2012, AMSAT-DL submitted its proposal for an amateur radio payload. Unfortunately, important positions on the antenna deck and with the payloads were already occupied at this point. There was also an approach for a Ka/Ka relaying transponder, but its use would have been limited to two small spot beams to northern Germany and southern Germany. At the time, this did not seem justifiable to our members and the amateur radio community in terms of the cost/benefit ratio. After it became clear that an amateur radio payload on the Heinrich Hertz satellite in the proposed form was not feasible, the proposal was finally withdrawn in September 2012.

Miraculously, however, a new window opened just a few months later! Initial talks and contacts were held as early as December 2012, which ultimately led to an amateur radio payload on the Es’hail-2 satellite, also known as Qatar-OSCAR 100 or QO-100. Es’hail-2/QO-100 was launched aboard a SpaceX Falcon 9 rocket on November 15, 2018. This project is a joint initiative of the Qatar Satellite Company, the Qatar Amateur Radio Society and AMSAT-DL. The satellite was built by Mitsubishi Electric Corporation in Japan and is located in a geostationary orbit at 26° East.

AMSAT-DL’s ERMINAZ Satellites Complete IARU Frequency Coordination

AMSAT-DL’S ERMINAZ satellites have completed frequency coordination with the IARU.

The ERMINAZ mission is a syndicated multi-PocketQube mission with a total of 7 PQs under the leadership of AMSAT-Germany, which also holds the launch contract with RFA under DLR support. The project is in collaboration between AMSAT-DL, AMSAT-EA (Spain), ESERO-Germany (Bochum Observatory) and Libre Space Foundation (Greece). The mission is to promote, advance and develop knowledge about space and amateur radio. ERMINAZ-1U & ERMINAZ-1V will transmit telemetry, images, provide a digipeat/store/forward functionally to all radio amateurs worldwide. ERMINAZ-1U will operate in the UHF amateur satellite band, while ERMINAZ-1V will operate in the VHF amateur satellite band. Only non-proprietary, open source and documented protocols, accessible to radio amateurs, will be used. This includes CCSDS telemetry, CW beacon, SSDV images, digipeater, AX.25 und possibly other modes. Telemetry and sensor data from radiation sensor and triaxial accelerometer / gyroscope / magnetometer will allow any radio amateur to participate by extending his knowledge about space. In addition, a digipeater and store & forward function will allow licensed radio amateurs to use ERMINAZ-1U/1V as a relay to communicate with other radio amateurs worldwide. The mission will conduct several experiments with different types of modulations, bandwidths, data rates and framing schemes: GFSK with data rate from 9600 up to 19200 GFSK with data rate from 9600 up to 19200 bits/s GMSK with data rate from 9600 up to 19200 bits/s BPSK with data rate from 9600 up to 19200 bits/s QPSK data rate from 19200 up to 38400 bits/s Frames will using three different framing schemes configurable upon the mission requirements: CSDS (residual or suppressed carrier) or IEEE 802.15.4 (preamble, sync) or AX.25. Planning a launch by RFA-Rocket Factory Augsburg AG from SaxaVord Spaceport into a 500km polar orbit not earlier than August 2024 together with UNNE-1 (HADES-E) and MARIA-G (HADES-F) from AMSAT-EA and QUBIK 5 from LibreSpace.

LoRa Digipeater Satellite from the U. S. Naval Academy Scheduled for 2025 Launch

A 3U CubeSat. USNA-16 will provide UHF LoRa digipeater service to the amateur radio service. Additionally, USNA-16 is a university-student educational amateur radio mission. It will test a modular CubeSat design and integration, as well as the efficacy of student-designed passive magnetic pointing scheme for S-band operation. INCHsat payload will provide UHF service to the amateur radio service. In addition INCHsat payload is a university, student lead, educational amateur radio mission. It will test custom designed and built components. Specifically it will test a custom on-board computer, a custom radio (based off the OpenLST), a custom motherboard, and a custom antenna deployment system. USNA-16 is a student educational amateur radio mission. It will test a modular CubeSat design and integration, as well as student-designed passive magnetic pointing scheme. TT&C will occur at UHF (437.235 MHz, will be designated as UHF-TTC in this document) and data downlinks will occur at 2.42GHz, both within the amateur bands and both using the LoRa protocol. This will be the first satellite launched by USNA using LoRa, with a potential future application of APRS over LoRa. USNA-16 will also provide UHF LoRa digipeater service at 437.235 MHz to facilitate communication between amateur operators. INCHSat is a student educational amateur radio mission built by students at the University of Maryland, including the licensee, KC3VBJ. There are no paid employees. The main goal is to enhance the aerospace skills of students in a professional context. The students are learning about satellites and space mission development and space communication by designing, building, and launching a payload onboard a cube satellite. The payload consists of a custom onboard computer, the radio, basic sensors, motherboard, and an antenna deployment system. Communication with the payload will be performed on the 437 MHz band from a ground station that will be constructed on the UMD campus. This payload radio (437MHz) will be designated as UHF-PLD in this document. USNA-16 will have a LoRa digipeater to serve the amateur satellite community. LoRa offers low-power beyond-line-of-sight digital UHF communications to the amateur community. Additionally, USNA-16 is a student educational amateur service mission that communicates on amateur frequencies. This will be the first satellite launched by USNA using the LoRa protocol, with a potential future application of APRS over LoRa. INCHsat payload is for the purpose of the training of UMD students in the construction and development of aerospace components. It also tests the components that we have developed on our own for future missions and research purposes with no commercial benefit. INCHsat payload will have a radio based on the open source OpenLST from Planet Labs to serve the amateur satellite community. INCHsat payload is also a student educational amateur service mission that will be communicating data obtained on amateur frequencies. Pending the mission success the code and schematics of the components used will be published as a cheaper alternative for amateur teams looking to launch a cube satellite.

Satellite Shorts from All Over

+ Shields up! On October 19, 1989, a monstrous X13 class solar flare triggered a geomagnetic storm so strong that auroras lit up the skies worldwide the following day. Had you been flying around the Moon at that time, you would have absorbed a dose that would most likely kill you within a month or so. This is why the Orion spacecraft that is supposed to take humans on a Moon fly-by mission this year has a heavily shielded storm shelter for the crew. But shelters like that aren’t sufficient for a flight to Mars. To obtain protection comparable to what we enjoy on Earth would require hundreds of tons of material, and that’s simply not possible in orbit. The primary alternative—using active shields that deflect charged particles just like the Earth’s magnetic field does—was first proposed in the 1960s. Today, we’re finally close to making it work. Fascinating full article at https://bit.ly/3PANp67 (ANS thanks ARS Technica for the above information.)

+ Not an April Fool’s joke: The U.S. Army has conducted a series of experiments, beginning in 1904 and continuing into the 1970s, on using trees as shortwave antennas. “It would seem that living vegetation may play a more important part in electrical phenomena than has been generally supposed. If, as indicated… in these experiments, the earth surface is already generously provided with efficient antennas which we have but to utilize for communications.” For complete details on how to turn the oak in your yard into a radiator for the 60 meter band, there’s a 55-page scientific paper at https://apps.dtic.mil/sti/tr/pdf/AD0742230.pdf (ANS thanks The Orbital Index for the above information.)

+ I’ve been workin’ on the railroad: Northrop Grumman Corporation was selected this month by DARPA to further develop the concept of building a moon-based railroad network as part of the broader 10-year Lunar Architecture Capability Study. The envisioned lunar railroad network could transport humans, supplies and resources for commercial ventures across the lunar surface. (ANS thanks The Orbital Index for the above information.)

AMSAT Prepares for Hamvention 2024

It’s that time again. Time to start making plans to attend Hamvention 2024 from May 17-19, 2024 in Xenia, Ohio. This year’s Hamvention theme is “Expanding our Community” and AMSAT plans to do exactly that by adding new members and recruiting more volunteers. Led by AMSAT Hamvention Team Leader, Phil Smith, W1EME, preparations are well under way. AMSAT, one of the larger Hamvention exhibitors, will again occupy 1,200 square feet of space at the north end of Building 1, also known as the Maxim building. This booth area has always been ideal for AMSAT because of the ample fresh air and easy access to the outdoor satellite ground station. Exhibits will feature members of the engineering team, CubeSatSim, Beginner’s Corner, merchandise sales, Youth Initiative, software demonstrations and membership sign-ups. Also featured at this year’s booth is information and sign-ups for the revitalized AMSAT Ambassador program.

AMSAT will host its annual AMSAT Forum on Saturday from 1:10 to 2:10 in Room 2. Moderated by Phil Smith, W1EME, Robert Bankston KE4AL, AMSAT President, will highlight recent activities within AMSAT and discuss some of our challenges, accomplishments, projects, and any late breaking news. AMSAT Engineering Program: Jerry Buxton, N0JY, AMSAT Vice President for Engineering, will talk about the Current and upcoming satellite missions. AMSAT Education: Alan Johnston, KU2Y, AMSAT Vice President Education Relations will talk about the AMSAT CubeSat Simulator. AMSAT Operations: Drew Glasbrenner, KO4MA, Vice President Operations, will discuss current satellites and operations. AMSAT Development: Frank Karnauskas, N1UW, Vice President of AMSAT Development, will report on AMSAT Youth Initiative and its features.

Another attraction will be the 15th annual AMSAT/TAPR Banquet on Friday at 18:30 EDT. This dinner is always a highlight of the TAPR (Tucson Amateur Packet Radio) and AMSAT (Radio Amateur Satellite Corp.) activities during the Dayton Hamvention. This year’s banquet speaker will be Bill Reed, NX5R, AMSAT Volunteer Engineer, who will highlight the forthcoming PACSAT digital communications payload.

The 2023 Hamvention attendance was 33,861, which is more than 2,000 greater than 2022 and even surpassed the previous pre-pandemic attendance record at the Greene County Fairgrounds and Expo Center of 32,472. This year’s attendance is expected to be another record breaker. As a bonus, this year’s Hamvention will also be the site for the ARRL 2024 National Convention.

AMSAT VP-Engineering Reviews GOLF Satellite Development

Recently AMSAT News Service had the opportunity to interview Jerry Buxton, N0JY, AMSAT Vice President of Engineering, about the GOLF satellites that are currently in development.

ANS: Jerry, the AMSAT engineering team is developing the GOLF (Greater Orbit, larger Footprint) satellites. What is the idea behind these satellites and the kind of functionality that will be added?

JB: “Our original thought was for GOLF is to teach us how to go to Highly Elliptical Orbit (HEO.) Higher orbits have greater challenges than the satellites for LEO orbits we have built most recently. These are challenges like the higher radiation environment that the satellite must endure and controlling the satellite at higher altitudes.

“We’ve had a significant additional requirement that has been added since GOLF was originally conceived. We must be able to deorbit the satellite on command. This is a pending FCC regulation. It is also likely that we will be required to move the satellite to avoid orbital debris in the future. To do this we have to be able to accurately know where the satellite is which requires a Global Navigation Satellite System (GNSS), which direction it is pointing which requires adding an Attitude Determination Control System (ADCS), and have a propulsion system to move it. This is not trivial.

“Of course, we want to add more and more capabilities which require more power.

“So, the purpose of the GOLF satellites is technology development, but they will have radios on board. Once they are up and we have proven the technology we will have another satellite that amateur radios operators can use.”

ANS: “What is the advantage of higher orbits?”

JB: “Most of our current satellites are LEO, so we have about a 10 to 15-minute window to work the satellite. With higher orbits, the satellites will have a larger footprint (the signal will cover a larger area of the earth) and will be available or visible for longer periods of time.

ANS: “Could you tell us a little more about how GOLF is being developed?”

JB: “We will design and build the systems if we can, and we will acquire (buy) the functionality if need to. We are also using a stepped approach to capability development. We may fly the Attitude Determination Control System (ADCS) on the first satellite, add the propulsion system on the next satellite and so on.

ANS: “Interesting! What else makes GOLF different from our previous satellites?”

JB: “GOLF-TEE will have a new 3U space frame with deployable solar panels, which will flop open and lock into place. The solar cell system is an in-house design. It will have 14 cells on the satellite space frame and 28 on the deployable solar panels for a total of 42 cells, a significant increase in available power.

“GOLF will have a radiation tolerant IHU (Internal Housekeeping Unit, or on-board computer.)
It uses an automotive grade 32 bit ARM processor which has two processors. One is the primary. If one locks up the other takes over. The computer cores are in different areas of the chip and are at 90 degrees to each other, which lowers the likelihood of radiation affecting both processors.

“We’re adding microwave bands with a 10 GHz downlink experiment for increased data speed, that can also be used as a transponder downlink. This is a purchased radio. It has been a little bit of a challenge to fit the SDR into GOLF because it doesn’t fit the normal layout.

“GOLF will be much more complex than the FOX satellites. This complexity will increase the cost. This is because of the added capability the engineering team is developing like the additional solar panels as well as the selection and integration of purchased items like the ADCS or the 10 GHZ SDR radio.”

ANS: “Wow, the GOLF satellites will be a give us exciting new capabilities! When will they be launched?”

JB: “The first is GOLF-TEE, which will be ready for launch in Q4 of 2025. GOLF-1 will be ready follow in Q4 of 2026. We should have some data and lessons learned from GOLF-TEE by then.

“Here is a little more detail on the launch; GOLF-TEE and GOLF-1 have been approved by NASA as sound concepts and eligible for the ELaNa program. This program will pay for launch up to $300k of launch cost (covers everything up to a 3U satellite to LEO) and they will look for a launch that we can ride on. (We don’t get to choose just when we launch.) A launch is not a guaranteed, but they always have found a ride for us.”

ANS: “Thank you, Jerry, for helping us understand these important new satellites!”

METEOR M2-4 Meteorology Satellite Readying for Operation

Low earth orbit meteorology satellites are usually overlooked as an easy way to get newcomers involved in amateur satellites. They transmit with high power and gain antennas so they are easily received with a simple dipole antenna and a $30 RTL-SDR dongle that plug into a computer that most everyone owns. They are always on and transmit data that is actually fun and usable: very clear pictures of ones’ own locale that is easily decoded with free software.

From this first experience, it is a simple jump to tracking and copying the ARISS voice and APRS repeaters, and from there getting a Technician class license and inexpensive handheld.

In addition to the NOAA low earth orbit polar meteorology satellites, the Russian METEOR M2-4 was recently added on February 29, 2024. It was launched into a 800km sun-synchronous orbit with a 98 degree inclination from the Vostochny Cosmodrome aboard a Soyuz 2 rocket.

Having achieved orbit, it is currently undergoing testing and calibration. There is currently no information when setup will be completed, but it did take several months for NOAA to get the NOAA-21 satellite running. Once it is functioning it will begin transmitting its low-rate picture transmission (LRPT) imagery on 137.1 MHz and/or 137.9 MHz. The antennas are right-hand circular polarization but are easy received with a home-made three-element yagi or even a simple dipole.

Complete information on suitable SDR receivers, and free receiving and decoding software can be found at rtl-sdr.com. A simple You Tube search on the topic will also provide you with enough demonstration videos to help get you started. More information at https://www.rtl-sdr.com/.

Satellite Tracking Rotator from Security Camera System

No stranger to AMSAT publications, Gabe Emerson, KL1FI, publisher of saveitforparts.com is at it again. This month Gabe has posted a 24-minute video on how to use parts from an old security pan-tilt camera mount to build an az-el satellite rotator.

The rotator motors are controlled by software based on the Australian School Amateur Radio Club Network (SARKNET) Rotator Mark I Arduino code. The software can be run on either an Arduino device or on a PC laptop. Gpredict is used in this example to track the satellites.

Gabe uses the rotator to steer a small dish but it looks strong enough to handle a lightweight yagi such as an Arrow or Elk if suitably counterweighted.

Even if you aren’t interested in building this az-el rotator, Gabe’s video is a fascinating look at how an inventive mind and resourceful scrounger can make something actually useful. Ham radio as it should be! More information at https://www.rtl-sdr.com/.

Changes to AMSAT-NA TLE Distribution for March 22, 2024

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. Elements in the TLE bulletin files are updated daily. TLE bulletin files are updated to add or remove satellites as necessary Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/

The following satellite has been added to this week’s AMSAT-NA TLE Distribution:

SONATE-2 – NORAD Cat ID 59112 Downlinks on 437.025 MHz, 145.825 MHz, 145.840 MHz and 145.880 MHz have been coordinated by the IARU. Thanks to Nico Janssen, PA0DLO, for the identification.

The following satellite has been removed from this week’s AMSAT-NA TLE distribution:

BeliefSat-0 NORAD Cat ID 58695 End of mission.

This mission was interesting as BeliefSat-0 is not a free flying satellite. Instead it is a “hosted payload” on a larger platform, in this case the spent upper stage of an Indian launch vehicle. The stage was modified such that it included solar panels and attitude control, so BeliefSat 0 and other payloads were designed to simply bolt on and plug in to a regulated power source. See https://www.isro.gov.in/POEM-3_Mission_achieves_Payload_objectives.html for details.

While BeliefSat-0 and its host POEM-3 remain in orbit for now, it appears that BeliefSat-0 has been shut down as there have not been any successful observations of it in SatNogs for several weeks. POEM-3 will reenter within the next few weeks “leaving zero debris in space” according to the Indian Space Resource Organization.

Satellite Shorts From All Over

+ Active satellite operator Alan Bowker, WA6DNR, became a silent key on March 8. Alan was one of the first Broadcasting majors at the University of Wyoming and began his career at KATI radio in Casper. He later worked for KCBS-FM and KGO TV in California. As microcomputers emerged in the industry, Alan evolved into a computer technologist, working at Northstar Computers, Fantasy Records, and Dolby Laboratories. During the winter months of 1983 and 1984, he spent time in London as computer consultant to Hollywood film filmmaker, Stanley Kubrick. In retirement, he turned into a travel photographer, touring worldwide and documenting his experiences in still photos and video. First licensed in 1966, he was a consistent voice on RS-44 and an avid experimenter on IO-117 and other digital modes from CM87 in northern California. He earned AMSAT GridMaster Award #62 of which he was very proud, while grateful to the many rovers who worked hard to make that happen for him. We will miss hearing Alan on the birds!

+ With the spectacular launch of SpaceX-30 on March 21, 2024, the HamTV system is now back on it’s on its way to the ISS. Although it is not expected that the HamTV equipment will be activated for at least a few weeks, the British Amateur Television Club (BAT) has created a new wiki page which gives a lot of information on how to receive, decode and display the DATV signals from the ISS. See https://wiki.batc.org.uk/HAMTV_from_the_ISS; there is also a discussion channel available on the site. [ANS thanks Graham Shirville, G3VZV for the above information.]

Their website, currently under construction, is https://amsat-hz.org/. AMSAT congratulates AMSAT-HZ on their establishment and wishes them the best of luck in their endeavors. [ANS thanks Abdul Alshahrani, HZ1DG for the above information.]

+ Tom Van den Bon, ZR6TG has been toying with this idea of adding a “Widget” to his Icom IC-9700. Playing with satellites requires various kinds of software that requires a fully fledged PC connected to the radio for tracking the satellite, controlling the rotator and automatically adjusting for Doppler effect. While all of that software works perfectly fine, Tom always wondered if there wasn’t a simpler solution which is always available and ready at the radio. Tom says, “I know there are a few satellite “controllers” available that allow you to do something similar, but I felt that those are either too specific (i.e., only one radio and one rotator) or was lacking some features. My idea around the Satellite Tracking widget is to try and combine everything I need in a single small display.” See Tom’s project report on his Raspberry Pi-based widget based at https://tinyurl.com/ANS-084-Widget.

First SONATE 2 Images Received

First images were received this week from the SONATE 2 satellite. A low-resolution Slow-Scan TV (SSTV) image that had been pre-loaded onto the satellite prior to launch was received on March 8. The first wide field of view earth image from the onboard camera was received on March 11. Both images can be viewed at https://www.informatik.uni-wuerzburg.de/en/aerospaceinfo/staff/kayal/research-activities/sonate-2/

[12.03.2024 First wide field of view image from SONATE-2]

SONATE 2 was built by students and faculty in the Aerospace Information Technology program at at Würzburg University in Germany. It was launched on March 4 as part of the SpaceX Transporter 10 mission from Space Launch Complex 4E in Vandenberg SFB, Calif.

Using Doppler measurements, Nico Janssen, PAØDLO, has identified SONATE 2 as object 59112. The telemetry downlink frequency is 437.0254 MHz, just slightly above the published target frequency of 437.025 MHz. Telemetry is in 9k6 G3RUH GMSK AX.25 using a protocol that may be downloaded from https://www.informatik.uni-wuerzburg.de/fileadmin/1003-ifex/2024/SONATE-2_protocol_definition_for_radio_amateurs.xlsx

The SSTV downlink is at 145.880 MHz FM using the Martin M1 protocol. The satellite also carries an APRS digipeater for 145.825 MHz, but the digipeater is not yet active. A schedule for upcoming SSTV transmissions is published at https://www.informatik.uni-wuerzburg.de/aerospaceinfo/mitarbeiter/kayal/forschungsprojekte/sonate-2/information-for-radio-amateurs/

FUNcube Mode Change

The FUNcube team are pleased to announce that FUNcube 1 (aka AO-73) is out of Safe mode back in Eclipse mode as of March 11. “Eclipse mode” means that the transponder is normally operational only when the satellite is in eclipse, i.e. the solar panels are NOT being illuminated.

The nominal transponder frequencies are:

Uplink: 435.150 – 435.130 MHz LSB (Inverting)
Downlink: 145.950 – 145.970 MHz USB
Telemetry Tx: 145.935 MHz BPSK

(The passband may be up to 15kHz higher depending on on-board temps. Lower temperatures give higher freqs!)

Starship Lifts Off On Third Test Flight

SpaceX’s Starship vehicle lifted off on its third test flight March 14, making significant progress compared to its first two by achieving most of its planned test milestones.

The Starship/Super Heavy vehicle lifted off from the company’s Starbase site at 9:25 a.m. Eastern. The liftoff was delayed by nearly an hour and a half because of ships in restricted waters offshore. SpaceX reported no technical issues during the countdown.

[Starship lifts off on its third integrated test flight March 14. Credit: SpaceX webcast]

The Super Heavy booster fired all 33 of its Raptor engines for nearly three minutes before executing “hot staging”, with the Starship upper stage’s engines igniting while still attached to Super Heavy before separating.

The booster then performed burns to attempt what SpaceX webcast hosts called a “soft splashdown” in the Gulf of Mexico, where it would not be recovered. However, the landing burn did not appear to go correctly, and the company later said that the booster broke apart 462 meters above the ocean after lighting several Raptor engines for a landing burn.

The Starship upper stage performed its burn, placing the vehicle onto its planned suborbital trajectory. It avoided the fate of the previous Starship launch in November, when the vehicle broke apart late in its burn after catching fire while venting propellant.

While in space on its suborbital trajectory, SpaceX opened a payload bay door that will be used on later Starship vehicles for deploying Starlink satellites. It also performed an in-space propellant transfer demonstration as part of a NASA contract where it would move propellant from one tank within the vehicle to another. SpaceX said it was evaluating the data from both tests.

SpaceX had planned to perform a brief relight of a Raptor engine on Starship about 40 minutes after liftoff, but the company said on the webcast that this test was skipped for reasons not immediately known. The company later said the engine test was called off because of the vehicle’s roll rates.

Several minutes later, the vehicle started reentry. A camera mounted on a flap on Starship provided dramatic images of the reentry, relayed through Starlink satellites. Telemetry was lost about 49 and a half minutes after liftoff when the vehicle was descending through an altitude of 65 kilometers. SpaceX later said on the webcast that it lost contact through both its own Starlink satellites as well as through NASA TDRSS data relay satellites at the same time, speculating that the vehicle may have broken up.

While the mission did not achieve all its test objectives, the company considered the launch a success. “What we achieved on this flight will provide invaluable data to continue rapidly developing Starship,” it said in a statement.

NASA’s SpaceX Crew-7 Finishes Mission, Returns to Earth

The SpaceX Crew Dragon Endeavour spacecraft, with NASA astronaut Jasmin Moghbeli, KI5WSL, ESA (European Space Agency) astronaut Andreas Mogensen, KG5GCZ, Japan Aerospace Exploration Agency (JAXA) astronaut Satoshi Furukawa, KE5DAW, and Roscosmos cosmonaut Konstantin Borisov aboard, splashed down in the Gulf of Mexico off the coast of Pensacola, Florida, on Tuesday, March 12, 2024. Moghbeli, Mogensen, Furukawa, and Borisov are returning after nearly six-months in space as part of Expedition 70 aboard the International Space Station.

The Crew-7 mission lifted off  at 3:27 a.m. on Aug. 26, 2023, on a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. About 30 hours later, Dragon docked to the Harmony module’s space-facing port. Crew-7 undocked at 11:20 a.m. Monday, March 11, to begin the trip home.

Moghbeli, Mogensen, Furukawa, and Borisov traveled 84,434,094 miles during their mission, spent 197 days aboard the space station, and completed 3,184 orbits around Earth. The Crew-7 mission was the first spaceflight for Moghbeli and Borisov. Mogensen has logged 209 days in space over his two flights, and Furukawa has logged 366 days in space over his two flights.

[A thermal screenshot showing the successfully deployed four parachutes of the Dragon Capsule as it makes its descent on March 12]

Throughout their mission, the Crew-7 members contributed to a host of science and maintenance activities and technology demonstrations, including a number of ARISS amateur radio contacts. Moghbeli conducted one spacewalk, joined by NASA astronaut Loral O’Hara, replacing one of the 12 trundle bearing assemblies on the port solar alpha rotary joint, which allows the arrays to track the Sun and generate electricity to power the station.

The crew contributed to hundreds of experiments and technology demonstrations, including the first study of human response to different spaceflight durations, and an experiment growing food on the space station.

This was the third flight of the Dragon spacecraft, named Endurance. It also previously supported the Crew-3 and Crew-5 missions. The spacecraft will return to Florida for inspection and processing at SpaceX’s refurbishing facility at Cape Canaveral Space Force Station, where teams will inspect the Dragon, analyze data on its performance, and process it for its next flight.

The Crew-7 flight is part of NASA’s Commercial Crew Program and its return to Earth follows on the heels of NASA’s SpaceX Crew-8 launch, which docked to the station March 5, beginning another science expedition. That crew consists of Matthew Dominick, KCØTOR, Michael Barratt, KD5MIJ, Jeanette Epps, KF5QNU, and Alexander Grebenkin, RZ3DSE.

Satellite Shorts From All Over

+ NASA has terminated its OSAM-1 mission, a multibillion-dollar endeavor aimed at showcasing robotic satellite servicing technology in space, due to ongoing technical, cost, and schedule challenges. Originally intended to demonstrate satellite refueling, the mission expanded to include in-orbit assembly, incorporating a 16-foot robotic arm named SPIDER. Despite significant congressional funding, the project faced continual delays and ballooning costs, reaching $1.5 billion with an estimated additional cost of nearly $1 billion for launch. Changes in the satellite servicing market, with a shift towards alternative technologies like Northrop Grumman’s Mission Extension Vehicle, contributed to the cancellation. Maxar, the prime contractor for OSAM-1, faced criticism for poor performance, leading to delays and cost overruns, although the company cited other factors like the COVID-19 pandemic. The cancellation impacts approximately 450 workers at NASA’s Goddard Space Flight Center, prompting NASA to review strategies to mitigate workforce impacts and consider alternative uses for developed technologies. (ANS thanks Ars Technica, for the above information.)

+ China’s human spaceflight agency, CMSA, is progressing towards its goal of landing astronauts on the moon before 2030. The spacecraft developed for this purpose has been named Mengzhou, translating to “Dream Vessel,” for lunar missions, and Lanyue, meaning “Embracing the Moon,” for orbital travel. These names were selected through a public contest, with Mengzhou having a variant for low Earth orbit (LEO) carrying seven astronauts and a moon version transporting three astronauts into lunar orbit. The China Aerospace Science and Technology Corporation (CASC) is designing and building the spacecraft and lander, along with a new rocket, the Long March 10. The moon landing plan involves two Long March 10 rockets launching Mengzhou and Lanyue, rendezvousing in lunar orbit, with astronauts descending to the lunar surface. A 440-pound crew rover will accompany the lunar lander. Progress on various mission hardware is reportedly on track, including completed development of the primary spacecraft and technical proposals for launch and landing sites. Recently, models of the rocket, spacecraft, and lander were showcased at an exhibition in Shanghai. (ANS thanks Space.com, for the above information.)

+ U.S. regulators have approved ground rules for allowing SpaceX and other satellite operators to use radio waves from terrestrial mobile partners to keep smartphone users connected outside cell tower coverage. The Federal Communications Commission voted March 14 unanimously in favor of its Supplemental Coverage from Space (SCS) regulatory framework. SCS providers would operate as a secondary service to companies providing Mobile Satellite Services (MSS) with conventional frequencies already approved for use from space. This means an SCS operator would have to immediately cease operations if they interfere with an MSS provider or terrestrial telco with primary rights. (ANS thanks SpaceNews for the above information.)

+ A rocket made by a Japanese company exploded seconds after launch on Wednesday, in a spectacular failure for the start-up’s bid to put a satellite into orbit. Tokyo-based Space One’s 18-metre (60-foot) Kairos rocket blasted off in the coastal Wakayama region of western Japan, carrying a small government test satellite. But around five seconds later, the solid-fuel rocket erupted in fire, sending white smoke billowing around the remote mountainous area as orange flames raged on the ground, live footage showed. Space One said it had taken the decision to “abort the flight” and details were being investigated. (ANS thanks Space Daily for the above information.)

SpaceX’s Transporter-10 Successfully Launches Over Fifty Satellites

SpaceX successfully executed its tenth Transporter rideshare mission, showcasing the continued high demand for satellite deployment services. The flawless launch took place at Vandenberg Space Force Base, on March 4th at 5:05 p.m. EST, where a Falcon 9 rocket carried 53 small satellites into orbit. While this success underscores the persistent need for such services from satellite developers, it also brings attention to emerging challenges in maintaining space situational awareness.

Among the diverse payloads was SONATE-2, a 6U+ CubeSat developed by the University of Wuerzburg in Germany. This satellite serves as a technology demonstration for artificial intelligence hardware, software, and machine learning techniques, coupled with an educational component through the DLR School Lab. SONATE-2’s amateur payload includes a VHF transceiver and an AI payload with optical sensors, providing regular SSTV downlinks, an APRS digipeater, and CW beacon.

The mission aims to engage students in aerospace and computer science engineering programs, offering practical skills and participation in satellite operations. SONATE-2 reported successful operation, with over 1000 telemetry frames downloaded in the first day post-launch, indicating a safe and stable state of the satellite.

Startups such as Unseenlabs, Loft Orbital, Atomos Space, True Anomaly, Quantum Space, and Sidus Space seized the opportunity, deploying their first satellites. This diverse array of payloads highlights the industry’s commitment to pushing boundaries in space exploration. Another notable payload, MethaneSAT, developed by Ball Aerospace for the Environmental Defense Fund, aims to track global methane emissions with high-resolution precision, contributing to environmental monitoring efforts.

Despite the success of Transporter-10, challenges in space situational awareness have surfaced. Owen Marshall of LeoLabs highlighted a degradation in cataloging objects after launch, particularly in rideshare missions where the median catalog time can exceed two weeks. This delay poses risks to satellite operators’ communication capabilities, emphasizing the need for enhanced tracking capabilities in the era of growing satellite deployments.

As the space industry evolves, addressing these challenges becomes crucial to ensure the sustainability and safety of activities in Earth’s orbit. The success of SpaceX’s Transporter-10 mission underscores the industry’s vitality, but the spotlight on emerging challenges signals the need for continual innovation and collaboration to navigate the complexities of our expanding presence in space.

Vostochny Spaceport Sends Meteor-M2-4 Weather Satellite Into Orbit

On February 29, 2024, the Vostochny spaceport witnessed the successful launch of a Soyuz-2-1b rocket, inaugurating the first mission of the year from this spaceport. On board was the Meteor-M2-4 weather spacecraft, a notable addition to the Meteor-M series, alongside several secondary payloads, including an Iranian micro-satellite dedicated to Earth observation.

Developed by the Moscow-based VNIIEM Corporation, Meteor-M2-4, weighing nearly three tons, boasts advanced instruments designed for comprehensive monitoring of global weather patterns, the ozone layer, ocean surface temperature, and ice conditions. Recognized for its military applications by the Russian space agency, Roskosmos, this mission marked a significant stride in space exploration.

Meteor-M2-4 encountered delays in its journey, originally slated for a December 26, 2023 launch. However, due to multiple rescheduling, the liftoff finally took place on February 29, 2024. The spacecraft, delivered to the launch site on December 28, 2023, underwent meticulous preparations, including fueling and integration with the launch vehicle, ultimately culminating in a successful liftoff.

Following the standard ascent profile for Meteor satellites, the launch trajectory headed northwest over eastern Russia, reaching a near-polar orbit with an inclination of approximately 98.57 degrees. The fairing protecting the payload separated during the second stage operation, with subsequent stage separations carefully planned for safe impact zones in the Amur Region and the Sakha Republic.

The Fregat upper stage took charge of the final payload deployment, executing precise maneuvers over the Arctic and Antarctica. Approximately 59 minutes and 46 seconds after liftoff, the Meteor-M2-4 satellite was successfully released, accomplishing its primary mission. The Fregat then proceeded to deploy the secondary payloads into their designated orbits.

The Russian Meteor M2-4 satellite commenced transmitting weather images within the first day in orbit. Known for their accessibility to amateur users, Meteor M satellites operate around 137 MHz, making them receivable with a RTL-SDR dongle and suitable satellite antennas. The satellite also transmits in the L-band, enabling reception with a 60cm or larger dish and motorized or hand tracking. Unlike previous satellites in the series, M2-4 experienced a smooth launch and deployment, with reports indicating excellent signal strength and clear image reception in both VHF and L-band frequencies. Two-Line Elements (TLE’s) and the SatDump decoding software (https://github.com/SatDump/SatDump) have been updated to support Meteor M2-4, simplifying access for enthusiasts through Github updates.

Space historian Jonathan McDowell shared valuable insights into the flight, detailing each Fregat maneuver and its impact on the satellite cluster. While the majority of the secondary payloads adhered to the expected orbits, anomalies in the deployment of some SITRO satellites prompted further investigation. The launch of Meteor-M2-4 and its accompanying payloads stands as a noteworthy accomplishment for Russia’s space program, contributing significantly to global endeavors in weather monitoring, Earth observation, and satellite technology development.

(ANS thanks NASA for the above information)

+ SpaceX is aiming for the third test flight of its Starship rocket on March 14, as announced through a post on the X platform. The Starship vehicle comprises a stainless-steel reusable upper stage, also known as Starship, and a Super Heavy first-stage booster, standing over 400 feet tall together. A recent critical fueling test at the Starbase facility in Texas involved pumping over 10 million pounds of liquid methane and liquid oxygen into the rocket. The upcoming launch follows two previous test flights in April 2023 and November 2023, where Starship faced issues like failure to separate from the first-stage booster and a subsequent explosion of the Super Heavy. After the second test, the FAA identified seventeen corrective actions, all of which SpaceX claims to have completed, addressing issues related to leak reduction, fire protection, and propellant vent operations. The Starship and Super Heavy, designed for full reusability, are pivotal for NASA’s Artemis 3 mission to land astronauts on the moon by 2026. (ANS thanks Brett Tingley, Space.com, for the above information)

+ NASA has identified a growing air leak on the International Space Station (ISS) located at the end of the Russian service module. The leak, situated in Russia’s Zvezda service module, initially released one pound of air per day but accelerated to over two pounds daily in early February. Despite the increased rate, NASA assures that it does not currently jeopardize the safety of the ISS crew or impact the station’s operations. Collaboration between the United States, Russia, Europe, Japan, and Canada is underway to address the situation. Roscosmos, the Russian space agency, confirms ongoing monitoring and asserts that there is no immediate threat to the crew or the station itself. The leak is in a three-foot-long area and has prompted precautionary measures, including sealing off the affected vestibule to mitigate further air loss from the rest of the space station. (ANS thanks Will Sullivan, Smithsonian Magazine, for the above information)

+ The inaugural components for Europe’s new Ariane 6 rocket have reached the port of Pariacabo in Kourou, French Guiana, transported by the container ship, Canopée. Manufactured across Europe, the central core arrived on Canopée, which uses sails to reduce emissions and save up to 30% on fuel during its 10-day, 7,000 km journey. The rocket’s stages were produced in various European locations, with the main engine and stage integrated in Les Mureaux, France, and the upper stage and insulation in Bremen, Germany. Following transport, the components were offloaded and taken to the Ariane 6 assembly building, a few kilometers away, where they will undergo integration before liftoff. The boosters, already at Europe’s Spaceport, are P120C solid propulsion boosters similar to those used for the Vega-C rocket. The central core will be assembled horizontally and then transported to the launchpad, where it will be erected, followed by the addition of boosters and the upper stage, with the goal of a summer launch for Flight Model-1.
