AMSAT Receives Two ARDC Grants for Youth Initiative Program

Frank Karnauskas, N1UW, AMSAT Director/VP-Development is pleased to announce that two grant applications were approved this week by Amateur Radio Digital Communication (ARDC).

BuzzSat.com
The first grant is for additional software licenses for production of the BuzzSat.com series of online courses designed for high school students. The first course, “Introduction to Satellite Meteorology’ was introduced at Hamvention 2025.

The production cycle begins with content development by a volunteer subject matter expert. In the case of the satellite meteorology course, retired high school earth science teacher Eric Sonnenwald, N2XSE created content by harvesting open-source material, both text and illustrations, and organizing it into a frame-by-frame presentation.

From there the frames are loaded into a specialized educational authoring program that adds a complex assortment of interactivity tools that help make the learning experience engaging and effective. Constant interaction required of the student helps prevent the lessons from becoming a mind-numbing “next – next – next” page turning sedative.

The authoring software has several AI assisted capabilities including the ability to generate audio narrative for the text and to translate the courseware into up to seventy different languages.

The theme of the lessons is “Satellites in Space Help Us Live a Better Life on Earth.” Fourteen courses are planned for completion by the end of 2026. The courses are free to students, teachers, at-home educators, scouting leaders and lifelong learners of all ages.

You can experience the “Introduction to Satellite Meteorology” course now at www.BuzzSat.com .

KidzSat.com
The second grant is for production of a satellite-themed coloring book for younger elementary-age kids. The coloring pages in the book show how satellites play important roles in almost every aspect of modern life. Satellites and their role in agriculture, navigation, broadcasting, pollution control and wildfire fighting are a few of the twelve topics shown in the book.

Production of the coloring book began about a month before the application for the grant was made. So, the finished book cover as well as sketches for a few inside coloring pages were shown at the AMSAT Space Symposium held in October.

The coloring books will be available before the end of this year for download free-of-charge from the AMSAT sponsored www.KidzSat.com website.

Alan Johnston, KU2Y, Presents CubeSat Simulator 2025 Updates

During one of the always popular CubeSat Simulator (CSS) presentations, Alan Johnston, KU2Y, AMSAT VP-Educational Relations showcased recent improvements to the CSS at last months AMSAT Annual Space Symposium.

The AMSAT CubeSatSim, the CubeSat Simulator, is a small, low cost, spacecraft simulator that serves as a tool for academic education, public demonstrations and theory and design disciplines. It can be used in a classroom, lab or training setting to introduce the basics of satellite operations, or it can be used to teach Science, Technology, Engineering, Math (STEM) exercises.

The pace of development in 2025 was similar to 2024 with several new features rolled out. The v2.1 software release added two new telemetry modes: FunCube Mode and Cross Band Repeater Mode. In addition, the Fox-in-a-Box v4 Beta Raspberry Pi Ground Station disk image was also released.

Cross Band FM Repeater Mode
The CubeSatSim Cross Band FM Repeater mode uses the FM transceiver module in receive mode, with the squelch pin read by the Raspberry Pi Zero to detect a transmission. This mode utilizes the USB sound card connected to the Pi Zero 2 with the OTG cable, and the audio jumper from the Main board to the sound card provides the received audio to the Pi Zero. The Pi Zero 2 then connects the microphone input to the rpitx transmitter. One of the CubeSatSim antennas is receiving the UHF signal, the other is transmitting the VHF signal at the same time, just like a real CubeSat with an FM repeater.

The v2.0 software release had a Repeater mode, but you couldn’t turn it on and off with the pushbutton, and it was unstable in that the repeater function would stop working and require a reboot. It also had uplink and downlink frequencies in the UHF band which made reception difficult. The v2.1 software release has fixed these issues, and moves the downlink to the VHF band. This provides a “U/V” operation with an FM UHF uplink, VHF downlink similar to many AMSAT CubeSats such as AO-91 (RadFxSat / Fox-1B) and AMSAT-UK AO-73 (FunCube).

New FunCube Mode
The CubeSatSim now has a new FunCube Mode 7. This BPSK (Binary Phase Shift Keying) 1200 bps (bits-per-second) transmission mode emulates the AMSAT-UK FunCube CubeSat (AO-73) and several other CubeSats that also use this transmission including Nayif 1 (EO-88), UKube-1, and JY1 Sat (JO-97). The transmission is very similar to the Fox-1E BPSK 1200 bps transmission already supported by the CubeSatSim in BPSK Mode 3. However, it has a different data structure and error correction. Special thanks to Duncan Hills, the lead FunCube Dashboard developer from AMSAT-UK who provided technical details and support to get this code working! If you listen to this mode, it sounds similar to BPSK, except for every four seconds it sounds like there is a “beep” or tone.

To decode FunCube telemetry, you need a FunCube Dongle (FCDPro or FCDPro+) and decoding software (an RTL-SDR dongle will not work). For the FunCube satellites in orbit, there is a Windows Dashboard for each satellite that decodes the telemetry and uploads the data to the AMSAT-UK Data Warehouse. We don’t yet have a Windows Dashboard, but we do have a Raspberry Pi application which will decode it. It is part of the new Fox-in-a-Box-v4 beta image.

The telemetry data is a similar format to JY1 Sat (JO-97) with a camera image and telemetry data in each frame. Unlike the CubeSatSim SSTV mode 4 which uses tones to transmit image pixels in Scottie 2 format, FunCube uses SSDV to encode JPEG images suitable for packetization. It uses the Reed-Solomon codec written by Phil Karn, KA9Q. You can see the image come in block by block, and if a frame is lost, there is a rectangular dropout in the image. Otherwise, the image quality is perfect. This makes an interesting comparison with the analog SSTV Mode 4 in which the image quality degrades as the signal strength decreases.

Future Updates
We are also working on a software update for v2.2 which will add these capabilities:

  • Improved simulated telemetry providing more realistic data.
  • Support for humidity and gyroscope/accelerometer sensors attached to Pi Zero 2.
  • Simulated failures.

Activity Guides
In 2025, we released the first set of CubeSatSim Activity Guides. The problem statement for the Activity Guides is “I just built (or borrowed) a CubeSatSim. What can I do with it?” Activity Guides are step-by-step instructions for how to do a STEM educational activity using a CubeSatSim. Most work with just a CubeSatSim (or even just a Lite). Some are very easy to do, such as listening to the sounds of the different modes on a HT and/or looking at modes on an SDR waterfall. Others are more challenging such as doing telemetry analysis using FoxTelem. Activity Guides include questions for students to answer as they do the activity. Each also has an Instructors Guide which has example data and answers to the questions.

The CubeSatSim Activity Guides are released under a Creative Commons with Attribution license so anyone can edit and modify them as long as they indicate they were originally developed by AMSAT. This allows teachers to customize them and include them in their lesson plans.

ARISS 2025 Highlights Presented by Frank Bauer, KA3HDO

The 43rd Annual AMSAT Space Symposium & Annual General Meeting featured a special presentation of the Amateur Radio aboard the International Space Station (ARISS) by Frank Bauer, KA3HDO, ARISS Executive Director. The prerecorded presentation highlighted many accomplishments for the year 2025.

A major accomplishment was achieving 25 years of continuous Amateur Radio operation aboard the space station.

While celebrating that achievement, ARISS is aware of substantial changes happening in the space industry and embraces the shift towards commercial missions.

With the upcoming decommissioning of ISS in the next five to six years, ARISS is listening to its NASA and ISS U.S. National Laboratory priorities. As a result, ARISS has modified the emphasis of its mission as follow:

  • An independent backup communications capability for ISS
  • Boosts ISS crew morale through enriching youth, community and Amateur Radio engagement
  • Inspires, engages and educates K-16 youth in STEM/STEAM via 10-minute Amateur Radio contacts with the on-orbit crew – a workforce development powerhouse
  • During 4-6 month pre-contact preparations, students learn about space exploration and science research, space communications, radio science & technology using Amateur Radio and on-going ISS research activities
  • Youth contacts keep astronauts proficient in ARISS radio operations and ground stations proficient in support of ISS backup communications.

The main ARISS prime initiatives continue to be STEM/STEAM education, spaceflight hardware development and spaceflight operations. Now, ARISS 2.0 educational vision for the future is to inspire, engage and educate students and lifelong learners. This means:

  • More extensive educational outcomes for all
  • Engaging educational projects and lesson plans
  • Multiple space stations on ISS and commercial missions, and
    Lunar orbiters and landers

Bauer described the initiative that are currently underway including:

  • The ARISS payload is now a facility on ISS, enabling partnerships to employ ARISS facility
  • Expansion to Axiom commercial space station flights
  • Expansion to Crew Dragon via Fram2Ham missions
  • More SSTV opportunities
  • Educational Extension initiatives
    • STEREO/SPARKI kits
    • ARISS STAR astronaut contacts
    • Student Mission Control program

Frank then spoke in detail about several outstanding successes for the year such as the Fram2Ham mission and the ever popular slow-scan television (SSTV) operations. Both events enjoyed exceptional exposure and impressive participation by students around the world.

Bauer went on to thank NASA, the ISS U.S. National Laboratory, the ARRL and AMSAT for financial and in-kind support and to Amateur Radio Digital Communications (ARDC) for critical resources.

Changes to AMSAT-NA TLE Distribution for October 31, 2005

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. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

This week there are no additions or deletions to the AMSAT TLE distribution.

Satellite Shorts From All Over

  • With SpaceX’s 10,000th Starlink satellite launched to orbit, and 8,562 active as of Oct 20th, a staggering 2/3rds of humanity’s active satellites in orbit are controlled by a single private company. [ANS thanks The Orbital Index for the above information.]
  • Two former NASA administrators criticized the agency’s current approach to using SpaceX’s Starship for the Artemis 3 crewed lunar landing, calling for an urgent redirection to reach the moon before China. In a fireside chat at the American Astronautical Society’s von Braun Space Exploration Symposium on Oct. 29, former administrators Charlie Bolden and Jim Bridenstine expressed skepticism that NASA’s current Artemis architecture. China aims to conduct the first launch of its Long March 10 rocket and a lunar-capable crew spacecraft next year, according to a top official. The announcement from the China Manned Space Engineering Office comes as the U.S. prepares to send its Artemis 2 crewed mission around the moon as soon as February 2026.[ANS thanks Space News This Week for the above information.]

ARISS SSTV Event Runs Through October 20, 2025

The ARISS team is working towards two short SSTV activations for October 2025. Both of these are expected to start on a Friday and end on the following Monday.

The first event is ARISS’ traditional celebration of the launch of the first artificial Earth satellite in 1957. The SSTV activation started on Friday, October 3 and will run to end on Monday, October 6. SSTV will be paused for a short time (~ 60 minutes) on Saturday October 4 for a special student voice contact.

The second SSTV campaign is tentatively scheduled to start on Friday, October 17, with a short pause (~60 minutes) for a special student contact on Saturday, October 18, and resume until completion on Monday, October 20.

This interval roughly coincides with the International Scouting Jamboree on the Air (JOTA) and the SSTV image theme is expected to deal with Scouting.

ARISS expects to offer separate electronic award diplomas for participants who receive at least one image from a campaign and submit it to the SSTV gallery.

Tentative times for the first event are:
2025-10-03 1140 UTC start
2025-10-04 1000 UTC pause for a school event
2025-10-04 1100 UTC resume
2025-10-06 TBD UTC stop

Four US Schools/Organizations Moved Forward in ARISS Selection Process

Amateur Radio on the International Space Station (ARISS) is pleased to announce the US schools/host organizations newly selected for 2026 ARISS contacts. A total of 4 of the submitted proposals during the recent proposal window have been accepted to move forward in the processes of planning to host a scheduled amateur radio contact with crew on the ISS.

The ARISS program anticipates that NASA will be able to provide scheduling opportunities for the 4 US host organizations during the Jan 2026 – June 2026 time period. They are now at work starting to implement their 4–6 month education plan which was outlined in their proposal. These STEAM based educational activities help prepare students for their contact as well as create an on-going exploration and interest in aerospace and amateur radio topics. They are also completing an acceptable equipment plan that demonstrates their ability to execute the ham radio contact. Once their equipment plan is approved by ARISS, the final selected schools/organizations will be scheduled as their availability and flexibility match up with the scheduling opportunities offered by NASA.

The schools and host organizations are:

  • ASU STEM Preparatory Academy Mesa, AZ
  • Conn Magnet Elementary School Raleigh, NC
  • The Center for Creativity, Innovation, and Discovery Providence, UT
  • EcoTarium Worcester, MA

The primary goal of the ARISS program is to engage young people in Science, Technology, Engineering, Arts and Math (STEAM) activities and raise their awareness of space communications, radio communications, space exploration, and related areas of study and career possibilities.

A Review of the futureGEO Workshop 2025 in Bochum

On September 19, 2025, the futureGEO workshop took place under the radome of the Bochum Observatory. Organized by AMSAT-DL with the support of ESA, the event brought together international experts, representatives of amateur radio organizations and dedicated radio amateurs who had previously declared their active participation in an appeal and submitted corresponding proposals. In the spring, AMSAT-DL had invited potential interested parties as part of an RFEI. The aim was to build on the experience gained with QO-100 and to jointly define the first concrete mission ideas for a future amateur radio payload in geostationary orbit.

The workshop was held as a hybrid event. The group was made up of one half who were present on site and the other half who took part online via ZOOM. Andrew Glasbrenner, K04MA, AMSAT VP – Operations represented AMSAT-USA at the meeting.

The purpose of the workshop was to collect, cluster and prioritize ideas:

  • Mission & Services – Which communication services and experiments should a new GEO payload enable?
  • Payload & antennas – What technical solutions are conceivable?
  • Ground station & operation – How can control and operation be organized?
  • User segment – Who should have access and how?

In a concluding reflection among the participants, it became clear how much QO-100 has revitalized and enriched the amateur radio community:

  • Affordable entry into microwave communication with low-cost SDRs and LNBs.
  • Development of open source software such as DVB-S2 encoders and decoders.
  • Educational projects from schools to schools contacts with Antarctica and other events.

The participants hope that radio amateurs can be even more involved in the construction of the hardware of a futureGEO with appropriate personal contribution, transparency and participation than was possible with QO-100 due to NDAs with the manufacturers and owners of the parent satellite.

The next steps are clear: The mission ideas developed in the workshop will be further concretized and should be available by the end of 2025 in the form of 1-3 consolidated mission concepts that are both technically exciting and attractive to the international amateur radio community and must also be technically feasible.

Changes to AMSAT-NA TLE Distribution for October 3, 2025

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. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/ .

This week there are no additions or deletions to the AMSAT TLE distribution.

Satellite Shorts From All Over

  • Suryono Adisoemarta, YD0NXX/N5SNN, Amateur Radio Organization of Indonesia, reports “September 28, 2025, was the 10th anniversary of IO-86 (Indonesia OSCAR 86) Satellite. The host vehicle, LAPAN A2 satellite, was launched from India using a PSLV rocket. This 10 years of almost problem-free satellite is beyond imagination, as the service year was designed only for 2 years. Currently the FM voice repeater payload is still working good , only the APRS digipeater is showing reduced sensitivity . The same digipeater box, a Tracker2, that was purchased at the same time in 2008 currently on my bench is also showing the same symptom. Hopefully we can have another 10 years of service from this satellite.” [ANS thanks Suryono Adisoemarta, YD0NXX/N5SNN, Amateur Radio Organization of Indonesia for the above information.]

  • M2 Antenna Systems Sales Manager Robert Brown, KR7O reports that LEO Pack antenna systems are back in stock and once again available in the AMSAT Store Despite the factory working nearly around the clock, the LEO Pack had been out-of-stock for several months due to a suddden increase in commercial and government orders. The good news is, at this time, there is no price increase. [ANS thanks M2 Antenna Systems Sales Manager Robert Brown, KR7O, for the above information.

The booth was appropriately decked out with the AMSAT Ambassador flag as well as other signage from previous events. An Arrow antenna was displayed on a Portable Rotation System plus a 3D printed model of the 3U GOLF-TEE satellite with deployable solar panels. An AMSAT CubeSat Simulator was operating during the event and sold on Sunday.

AMSAT provided a door prize, a copy of SatPC 32 software that was won by Roger Pushor, NK1I.

On Saturday afternoon, Burns Fisher presented “AMSAT Golf-TEE Software-How Does it Work” during the forum. His talk was about the flight software on Golf-TEE including how multiple processors are coordinated.

A second presentation, titled “SDR Transponder/Transceiver,” was delivered by Ray Roberge, WA1CYB. Ray is a member of the AMSAT Engineering Team.

AMSAT Announces Two New GridMaster Award Recipients

It is with great pleasure that AMSAT announces two new recipients of the GridMaster Awards in the past week.

Bruce Robertson, VE7PTN, has achieved the AMSAT GridMaster Award #74 by confirming all 488 maidenhead grid squares in the continental United States. In his announcement Bruce thanked “everyone for the QSOs, and especially the rovers—thanks for roving.” His recognition of the portable operators who make rare grids possible underscores the community spirit at the heart of this award.

GridMaster Plaque

Grace Papay, K8LG, has also earned the AMSAT GridMaster Award, becoming recipient #73. Like all GridMasters, this reflects years of dedication in working and confirming all 488 CONUS grids. Her achievement places her in the very small circle of operators who have reached this milestone.

Satellite Shorts From All Over

  • AMSAT Ambassador Tom Schuessler, N5HYP had a great opportunity to present a “Getting Started with Amateur Satellites” talk on Monday, August 25th to the Denton County Amateur Radio Association, DCARA, of Denton, Texas. There were at least 50 in attendance in the room plus a few more by Zoom. After Tom’s presentation Andrew Koenig, KE5GDB delivered a wrap-up report on Richardson Wireless Klub’s August 23rd high altitude balloon launch. Their craft had multiple amateur radio payloads and cameras on board. The balloon was launched from Old Celina Park in Celina TX, and ascended to a maximum altitude of 105,528 feet before bursting and (rapidly) descending back to the ground just north of Justin TX. The cross-band VHF/UHF repeater was the star of the show, with hams in all directions reporting clear communications including Johnson Space Center and Pearland to the South, Abilene and Amarillo to the West, and several stations in Arkansas to the Northeast. The report with some great images can be found on the K5RWK web site https://www.k5rwk.org/2025/08/24/rwk-high-altitude-balloon-launch-wrapup-august-23rd/ .

  • The RSGB 2025 Convention will be held on October 1-12 at the Kents Hill Conference Centre, Milton Keynes. The program is full of entertaining, intriguing and thought-provoking presentations and have been organized into three streams: Discover. Learn. Progress. The organizers are also excited to offer three workshops to help attendees learn and develop skills in a practical setting. Young hams who are under 21 you can attend the Convention free of charge. Attendees who are under the age of 16 you must be accompanied by a responsible adult. The presentations will be streamed live by the BATC and recorded for later viewing on You Tube. Streaming links will be made available as the event gets closer. Information on the complete presentation schedule and registration details can be found at https://rsgb.org/main/rsgb-convention-2025 . [ANS thanks the RSGB for the above information.]
  • The 5th Edition of the AM1SAT Biennial Contest Organized by URE and AMSAT-EA, will take place from September 15-21, 2025, as part of the activities of the IberRadio 2025 event, the 10th Radiocommunications Fair, the largest amateur radio event in Spain (see https://www.iberradio.es/). The goal is to establish the longest possible radio contacts during the competition through satellites orbiting Earth in LEO orbits. In total, the 15 longest contacts during the competition period will be evaluated. The use of a GEO satellite is deliberately avoided, as equal treatment among participants cannot be guaranteed either on the GEO satellite itself or worldwide. Complete rules for the contest can be found at https://www.amsat-ea.org/app/download/14094293/AM1SAT+2025+Contest+-+English.pdf . [ANS thanks AMSAT-EA for the above information.]
  • SpaceX’s Dragon cargo spacecraft successfully finished a test reboost of the International Space Station on September 3rd according to NASA. The freighter fired two of its Draco engines for 5 minutes and 3 seconds during the maneuver, agency officials wrote in a Wednesday statement. The ISS orbits roughly 250 miles above Earth on average but naturally falls back to our planet due to atmospheric drag. Visiting cargo spacecraft therefore take on the job of lifting the orbiting complex higher every few months. On Wednesday, Dragon’s efforts got the station to an orbit of 260.9 by 256.3 miles according to NASA. “The new boost kit in Dragon will help sustain the orbiting lab’s altitude through a series of longer burns planned periodically throughout the fall of 2025,” agency officials added. NASA has said these tests will also be important for another SpaceX job down the road: deorbiting the ISS itself.

ARISS SSTV Event Starts July 14

Amateur Radio on the International Space Station (ARISS) has announced Slow Scan Television (SSTV) Series 28 to run from July 14-20, 2025.

The theme will be the Apollo Soyuz mission and STS-51F which pioneered SSTV on Shuttles.

This series of 12 images will be transmitted from the ISS on 145.800 MHz using PD120 encoding. Software needed to decode the pictures is free and is available for PC’s, Mac’s, Android smartphones, and iPhones. Search “SSTV software” on Google and your phone’s app store for a variety of options.

Transmissions from the ISS are powerful enough so images can be received with a handheld radio and its stock rubber duck antenna, albeit quite noisy. The addition of a simple homemade 3-element beam to the handheld can produce in pixel perfect images. Persons who are not familiar with SSTV operations can visit https://amsat-uk.org/beginners/iss-sstv/.

You are invited to upload decoded images in the ARISS gallery, area “ARISS Series 28 Apollo Soyuz and STS-51F” at: https://ariss-usa.org/ARISS_SSTV/. Once you’ve submitted your pictures, just click on the dedicated button to apply for the official ARISS SSTV award.

Transmissions will begin on Monday, July 14 at 09:15 UTC (05:15 AM Eastern time). Transmissions will cease on Sunday, July 20 at 18:00 UTC (2:00 PM Eastern time).

ARISS Call for Proposals for School Contacts Began July 9

The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2026 and June 30, 2026. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan.

Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session.

The deadline to submit a proposal is August 29th, 2025. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org.

An ARISS Introductory Webinar session will be held on July 30th at 7 PM ET. The Zoom link to sign up is: https://us06web.zoom.us/meeting/register/E0qy2calSqudqufl09PL8A

Questions should be directed to [email protected].

SDR Provides New Capabilities For Next AMSAT CubeSats

Rich Gopstein, KD2CQ and Bill Schell, W2WZ highlighted new systems aboard AMSAT’s new GOLF CubeSat at Hamvention 2025. Rich detailed the software defined radio (SDR) module while Bill explained how the SDR communicates with other systems on the upcoming GOLF satellites.

Rich explained, “The diagram above is a block diagram of the GOLF-TEE 3U CubeSat. The purple rectangle located in the middle of the diagram represents a (SDR). The Fox series of satellites before had transponders. Some were FM transponders. They acted like a repeater up in the sky. A single FM channel up with a single FM channel down. Other Fox satellites had linear transponders with wide bandwidths for several SSB or CW signals. Whatever you sent up to the satellite, either on 2 meters or 440, would come down on the other band.

“You could communicate with people that way, operate either FM or linear transponder, but that’s all you could do with a transponder. On the other hand, the SDR allows us to do much more interesting things. Instead of the radio being permanently built into the hardware like it was in the Fox series, with an SDR it’s all done in software. We don’t have to change the hardware to implement different modes like SSTV or any of the voice, data or image operations we want to try. With an SDR we can do it in software. It’s much easier much quicker to do.

“The SDR communicates with the RF matrix, represented by the light gray rectangle to the right of the SDR. The SDR communicates and is controlled by other circuits in the satellite through the Controller Area Network (CAN) bus shown to the left of the SDR. That control bus is used to activate and deactivate the radio system as well as command it to perform a variety of operations.”

Specifically the SDR for the first GOLF satellites is the Ettus Research™ E310 Universal Software Radio Peripheral (USRP™). Rich explained, “The Ettus 310 SDR has two receive and two transmit antenna connections, which gives us a lot of flexibility in terms of what we want to do. For example, we can create cross-band transponders with it. We will use the radio at 5 GHz and 10 GHz, but it can’t do 10 GHz natively. We need to implement some RF hardware externally to increase the original frequency range to 10 GHz.

“The Ettus runs on a Linux operating system so we will use GNU Radio software to program radio functions. So, if we want to have the radio operate as a transponder, for Morse code, telemetry, SSTV, or whatever, we can do it can through programming.”

It is a free and open-source software development toolkit that provides signal processing blocks to implement software radios. Gopstein remarked, “GNU Radio makes programming easier! The talent and skills of AMSAT engineers are a precious resource. The GNU building block approach saves time while elevating consistency, quality and production rates for the benefit of all AMSAT satellite end users.

“We’re using GNU Radio to support radio necessities such as the spacecraft transponder, telemetry and other modes of data transmission for the GOLF satellites. These are just a portion of the functions we’re capable of using.

“Because the Ettus E310 SDR connects to the RF matrix, various antennas on the satellite can be connected to the SDR. As I said before, the output from the SDR will have a 10 GHz frequency converter and we will also have a solid-state power amplifier. That combination will increase frequency and output power for transmission at 10 GHz then sending the RF to an X band patch antenna.”

“One element of RF operation that we’re definitely going to try with the SDR is a 1 megabits per second (Mbps) data transmission. Another exciting experiment with the SDR could be ‘five-and-dime’ 5GHz/10GHz microwave radio transponder. On future missions, we expect to use the SDR to try all sorts of other functions with the SDR, yet to be determined,” Rich concluded.

Next, Bill Schell, W2WZ went on to say, “This block diagram is a detailed look at part of the original diagram. It shows the Ettus E310 SDR connected to the main control processor of GOLF-TEE, the RT-IHU (Radiation Tolerant Internal Housekeeping Unit). The two are connected over the CAN bus, over which messages flow in each direction.”

“The RT-IHU control software communicates with a python application running on the E310 called ‘SDR Server’. This application receives request messages from the RT-IHU to execute various SDR related actions. It also sends E-310 related status and telemetry information back to the RT-IHU”, Bill added.

According to Bill, “One of the most important actions the RT-IHU requests through SDR server is to start and stop GNU radio flows on the E-310. These flows are the software that implement the radio functions of the SDR. A flow might implement a transponder, the transmission of a periodic morse code ID, or the transmission of a data file to a ground station. Flows are created from building blocks in the GNU radio user interface. Common types of blocks include signal sources, filters, modulators, demodulators, FFT’s, math operations, etc. Blocks are combined to implement a flow which accomplishes a particular radio or signal processing task.”

“Other actions the SDR server performs are the sending of IMU and temperature data to the RT-IHU, receiving a file for later transmission (by a flow), shutdown, and other housekeeping functions”, Bill concluded.

Changes to AMSAT-NA TLE Distribution for July 11

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. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

This week there are no additions or deletions to the AMSAT TLE distributions.

ARISS NEWS

Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide.

There are no scheduled contacts at this time.

The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down). If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

The packet system is also active (145.825 MHz up & down).

As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time.

The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html

The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html
