AMSAT Publishes “Satellites in Space” Coloring Book

As part of its Youth Initiative, AMSAT just published its “Satellites in Space” coloring book on www.BuzzSat.com. The free coloring book is available at no charge in both English and Spanish language versions.

The complete title of the coloring book is “Satellites in Space Help us Live a Better Life on Earth.” This theme shows how satellites play an important role in virtually every aspect of modern life. The book includes twelve two-page spreads that illustrate different roles that satellites play and the benefits they provide.

Coloring Book

For example, one spread explains “Helping Farmers Grow bountiful Crops – For Healthy Meals on Every Table!” Another spread features teenagers using Amateur Radio “Sharing Messages and Pictures ‘ With Friends Around the World!”

The complete list of topics include:

  • Agriculture
  • Broadcasting
  • Communications
  • Climate Change
  • Pollution Control
  • Fighting Wildfires
  • Preserving Wildlife
  • Space Exploration
  • Navigation
  • Meteorology
  • Research on the ISS
  • Search and Rescue

Each topic also includes a one-page discussion guide for adult leaders to use when working with youth and the coloring books.

Frank Karnauskas, N1UW, AMSAT VP-Development explains, “We have produced the coloring book for several reasons. First, it is the ‘right thing’ to do. We must educate and encourage youth to become active contributors in satellite and communication technology. Second, It helps us satisfy part of our responsibilities spelled out in AMSAT’s Articles of Incorporation to encouragement of skills, even at the earliest stages of our youth’s development. Third, it begins to develop an awareness in young people of amateur satellites and amateur radio. We, of course, won’t convert every young person into and amateur radio operator and an AMSAT member, but we will get our fair share. The earlier we start, the better our chances.

Teenager with Icom IC-9700

“There are two very unique aspects of AMSAT’s Youth Initiative. First is it is a ‘community based’ program. The materials are designed so that any parent, scouting leader, amateur radio club or teacher can use the materials as they stand. It does not require buy-in by a school system for get started.

“The second unique feature is that, although its ultimate goal is to interest kids in amateur satellites ans amateur radio, the materials appeal to a broader spectrum of youth’s interests. If they have an interest in current events affecting our planet or in their future careers, we have at least begun a dialog with which we can nurture their possible interest in satellites and communications technologies. And, if we haven’t won them over along the way, at least we have educated them in some aspects of STEM and perhaps even inspired them.

“The Spanish language version of the coloring book is our first step in attempting to publish the coloring book in as many languages as there are AMSAT sister-organizations. I am interested in exchanging ideas with representatives of AMSAT organizations around the world to help make this happen.

“AMSAT thanks Amateur Radio Digital Corporation for a generous grant to make this project possible.”

Persons interested in viewing the coloring book and perhaps downloading copies for the kids can learn more at www.BuzzSat.com.

AMSAT-DL’s Peter Gülzow, DB2OS Honored

Peter Gülzow, DB2OS, was recently honored as one of the “Top 100 of the Table 2025/26”: The 100 key figures in the space scene, and among the ten most influential leaders in the associations category. This recognition was bestowed by by the editors of Space.Table. The Table.Briefings editorial team is a diverse group of talented editors who are experts in their field and bring a wide range of experience and knowledge.

Peter commented, “The space editors of Table.Media have honored me as one of the ten formative minds in the associations category. However, I see this recognition not only as a personal award, but above all as a tribute to an extraordinary community: AMSAT!

“For more than 50 years, the global AMSAT community has been developing, building and operating small satellites – driven by voluntary commitment, enthusiasm for space travel, passion, technical excellence and a clear vision. If AMSAT were a ‘space nation,’ we would rank about 10th in the world with over 130 amateur radio satellites launched. This is a remarkable result for a non-governmental organization run by volunteers.

“AMSAT was and is an incubator for technology, training and entrepreneurial thinking in the space sector. Generations of radio amateurs, students, engineers and founders have been shaped by this platform.

“However, against the backdrop of growing commercial mega-constellations and increasing regulatory consolidation, a central question arises: What role will non-commercial, experimental satellite radio play in the orbit system in the future?
Amateur radio via satellite is not a nostalgic relic. It is:

a low-threshold access to space travel for the next generation,
an experimental testing ground for new technologies,
an international cooperation model beyond geopolitical tensions, and a building block of technological sovereignty – also in Europe.

“This requires reliable frequency protection, regulatory planning security and a political framework that does not suppress voluntary innovation structures, but recognizes them as part of the space ecosystem.”

[ANS thanks AMSAT-DL for the above information.]


“Satellites and Pollution Control” Added to BuzzSat Online Courses

Retired school science teacher and AMSAT volunteer Eric Sonnenwald, N2XSE, has been hard at work finishing AMSAT’s third online course “Satellites and Pollution Control.”

The first two course published, “Introduction to Satellite Meteorology” and “Satellites and Climate Change” have gone through their initial test reviews and are now fully active. The pollution control course is online but not promoted until its review cycle is completed.

Pollution Control

Two additional courses, “Satellites and Conservation” and “Satellites in Wildfire Fighting” are nearing completion and will be online shortly.

These courses are designed for teenage students and are available at no charge to any parent, group leader or teacher.

Future titles planned include:

  • Amateur Satellites
  • Building a Ground Station
  • Satellite Telemetry
  • Broadcasting
  • Navigation
  • Point-to-Point Communications
  • Space Exploration
  • Research in Space
  • Search and Rescues
  • And, many more.

Persons who are subject matter experts in any of the above fields or any other topics that you think are important to STEM education are invited to email volunteer [at] AMSAT [dot] org. The AMSAT Youth Initiative has a great working team and welcomes more volunteers to help stimulate youth interest in amateur satellites and amateur radio. Try the online courses at www.BuzzSat.com.

Changes to AMSAT-NA TLE Distribution for February 20, 2026

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

  • Flatsat 1 is a hardware based training platform designed to be vulnerable — on purpose. It’s built for hackers, engineers, and space enthusiasts who want to dive deep into space-grade systems, learn cybersecurity concepts, and prototype their own payloads. The board contains an RP2040 MCU for comms and simulation, 2 x SX1262 LoRa radios for realistic space-ground communication scenarios, LIS2DH 3-axis accelerometer for sensor data emulation and tampering challenges, and a BME280 environmental sensor for telemetry testing. All firmware and documentation is open source. Boards are scheduled for availability on April 30, 2026, but pricing information is not yet announced. [ANS thanks Electronic Cats for the above information. See the full description at https://electroniccats.com/flat-sat/.]
  • The Civil Aviation Authority of The Bahamas (CAA-B) has approved the resumption of Falcon 9 first-stage touchdowns in the nation’s waters. The decision ended a lengthy review spurred by a test flight mishap with SpaceX’s Starship megarocket, which rained debris down on parts of the island nation nearly a year ago. SpaceX can land its rockets in The Bahamas again — and will do so very soon, if all goes according to plan. [ANS thanks Space.com for the above information.

  • A new SpaceX tool for tracking satellites and other objects in low Earth orbit (LEO) could help prevent future satellite collisions, and it’s attracting significant industry interest by requiring users to provide data on their own satellites. The system, known as Stargaze, uses the star tracker cameras on SpaceX’s near-10,000 Starlink satellites to image objects in LEO, creating a detailed map of where everything is at any one time. That information could make a huge difference in avoiding satellite collisions. [ANS thanks Yahoo!Tech for the above information.

FO-29 Operating Schedule for February 2026

The FO-29 Control team sometimes receives requests regarding the operation of Fuji No.3, but as they have already reported, more than a quarter of a century after its launch, the situation remains unstable. They regret that they are unable to operate Fuji No.3 in accordance with your wishes under these circumstances, and they ask for your understanding and continued use of her.

During February, the control team plans to send a command to turn on the transponder at the following times, but please be advised that if it is not turned on for more than 2 minutes after they start sending the command, they will terminate the command work.

February
6th 23:14-
7th 22:19-
13th 22:03-
14th 22:53-
20th 22:36-
21st 23:27-
27th 23:10-
28th 22:12-

Note: FO-29 will enter full sunlight around March 9.

Editor’s note: Full sunlight will hopefully allow continuous operation of FO-29’s linear transponder.

ESA-Led CCSDS Competition Registration Now Open

David Johnson, G4DPZ, AMSAT-UK Honorable Secretary reminds everyone that the ESA-led Competition, in collaboration with AMSAT-UK, AMSAT-DL, CCSDS, and Goonhilly Earth Station, is now open to European and Canadian teams and individual participants.

Entrants will work on real space communication standards, including CCSDS and LunaNet protocols. The European Space Agency (ESA) is launching a pilot program on behalf of the Consultative Committee for Space Data Systems (CCSDS). This outreach initiative aims to strengthen engagement with the European amateur satellite and academic communities.

Participants may choose to develop implementations for either of these CCSDS protocols:

LunaNet Signal-In-Space (LSIS-AFS)
Defines how lunar orbiters or surface systems broadcast a unified navigation and timing signal to support future missions on and around the Moon. Develop a functional concept or prototype demonstrating signal design, transmission, interpretation, or application for lunar missions.

Space Communications Session Control (CCSDS 235.1)
Defines how space missions establish, manage, and conclude communication sessions between spacecraft and ground systems. Create a practical, interoperable reference implementation aligned with the CCSDS 235.1 standard.

Winners will receive an invitation to attend a CCSDS conference, where they will present their results to the international CCSDS community.

An in-person workshop at Goonhilly Earth Station will be available to interested participants, providing a unique environment for collaboration, expert guidance, and accelerated development.

Help Wanted: Feature Story Editors & Video Editor

Sharing news of AMSAT activities, especially the work of the AMSAT Engineering Department, is an important function that supports AMSAT’s information and education mission. It is also an important tool for retaining current members, recruiting new members and for fund raising.

Frank Karnauskas, N1UW, AMSAT VP-Development is asking, “Do we have two volunteers who can step up and spend just a few hours a week to help keep our information channel flowing?

“For the Feature Story Editors, we have a pool of information that we’ve collected from Hamvention and Symposium presentations that can be quickly converted into short stories for publication in the ANS Weekly Bulletins and into feature stories for The AMSAT Journal. We typically start with a video or at least an audio recording of the presentation which you would convert into a written transcript using an application that we provide. The editor then uses the transcript and the author’s original PowerPoint slides to create the final articles.

“We also have the need for someone to write press releases for other AMSAT activities such as Educational Resources, the Youth Initiative, annual reports and so on.

“For the Video Editor, again we have a collection of videos from presentations that simply need opening titles to be added and a bit of “tuning up” inside the presentations themselves. There is no need for expensive software or especially super high power computers. Free software that is remarkably powerful but easy-to-learn is available. If a person is interested we would also welcome someone to create promotional video shorts or other programs they are willing to create.

“We’re not asking anyone for a life-long commitment to these positions. Anyone who is willing to say, ‘Hey, I can do five or ten stories’ would be a hero in my book.”

Persons interested in learning more about how they can make an important contribution can contact Frank at volunteer [at] amsat [dot] org.

Using Neural Networks to Recover Satellite Signals

Edwin Temporal has shown how his proprietary neuromorphic engine, GhostHunter (Anti-LIF), is being used to recover satellite data buried in the noise floor, which typical DSP methods would fail to do.

To recover the signals, Edwin uses trained Spiking Neural Networks (SNN). SNNs are artificial neural networks that draw further inspiration from nature by incorporating the ‘spiking’ on/off behavior of real neurons. Edwin writes:

“My engine has successfully extracted and decoded structured data from high-complexity targets by mimicking biological signal processing:

  • Technosat: Successful decoding of GFSK modulations under extreme frequency drift and low SNR conditions.
  • MIT RF-Challenge: Advanced recovery of QPSK signals where traditional digital signal processing (DSP) often fails to maintain synchronization. “These missions are fully documented in the https://temporaledwin58-creator.github.io/ghosthunter-database/, which serves as a public ledger for my signal recovery operations. Furthermore, the underlying Anti-LIF architecture is academically backed by my publication on TechRxiv, proving its efficiency in processing signals buried deep within the noise floor.”

In the database, Edwin shows how his Anti-LIF system has recovered CW Morse code telemetry and QPSK data from noisy satellite signals.

While Edwin’s Anti-LIF is proprietary, he is offering proof of concept decoding. If someone has a 250MB or less IQ/SigMF/Wav recording of a signal that is buried in the noise floor, they can submit it to him via his website, and he will run Anti-LIF on it for analysis.

Advanced readers interested in AI/neural network techniques for signal recovery can also check out his white paper on TechRxiv, https://tinyurl.com/ANS-025-Neural-Networks where he shows signal recovery from signals buried in WiFi noise, as well as results from use in ECG and Healthcare applications.

Satellite Shorts From All Over

  • A key antenna in NASA’s Deep Space Network (DSN), one that was damaged last fall, is expected to remain offline until May. Then, it will be taken out of service again later this year for major upgrades. The DSS-14 antenna, a 70-meter dish at the DSN complex in Goldstone, California, was damaged Sept. 16 when it over-rotated, stressing cabling and piping. DSS-14 is one of three 70-meter antennas in the DSN; the others are located near Madrid, Spain, and Canberra, Australia. The 70-meter antennas are used to communicate with distant spacecraft or those experiencing technical problems. (ANS thanks SpaceNews for the above information.)
  • China suffered a pair of launch failures within 12 hours on Jan. 16 and 17. This included the loss of a classified Shijian satellite after a Long March 3B lifted off at 1655 UTC from Xichang Satellite Launch Center in southwest China. The China Aerospace Science and Technology Corporation (CASC) confirmed the failure around 12 hours after liftoff, stating that the Shijian-32 satellite had been lost following a third stage anomaly. Roughly 12 hours later, the Ceres-2 lifted off at 0408 UTC on Jan. 17. from the Jiuquan Satellite Launch Center in northwest China. Galactic Energy confirmed the loss of the debut flight, stating that an anomaly had occurred and that the specific cause is under further investigation.

AMSAT Youth Initiative: “Satellites and Climate Change” Course Now Online

The beta release of “Satellites and Climate Change” is now available online. This course is the second online course published as part of the AMSAT Youth Initiative’s series “How Satellites in Space Help Us Live a Better Life Here on Earth.”

The course was written by Eric Sonnenwald, N2XSE. Eric, a retired science teacher in Lake Hopatcong, New Jersey, is a graduate of Montclair State University with an M.S. in Geosciences and the former Science Curriculum Coordinator for Hardyston Middle School. In order to expedite the development of the courses and keep costs low, one of Eric’s most challenging tasks in creating the lessons is sourcing copyright-free graphics and related resources. Fortunately there is a relatively abundant pool of free materials available on government and college websites from which to draw.

Eric Sonnenwald, N2XSE (AMSAT)

From Eric’s content, other AMSAT volunteers use specialized software to format the content into an online presentation.

The “Satellite and Climate Change” course follows the “Introduction to Satellite Meteorology” course introduced at Hamvention 2025. Several improvements have been added to the lesson format including the ability to zoom in and enlarge complex graphics shown in the screens. This is an important addition since students often use smartphones or tablets with much smaller screens that desktop or laptop computers

The third course, “Satellites and Pollution Control” is scheduled for launch within the next week or two, followed by “Satellites and Preservation of Natural Resources” in January. In all, fourteen courses are scheduled for publication by the end of 2026.

Frank Karnauskas, N1UW, AMSAT Vice President-Development and creator of the Youth Initiative explains, “Our approach to getting youth interested in satellites and amateur radio is to attract their attention and participation in topics of current events and widespread interest. We explain how satellites are an integral component of almost every facet of modern living and from there introduce the concept of critical information provided by satellites, then telemetry, and communications. We provide access to experiences with satellite telemetry via amateur radio satellite ground stations to access ARISS packet and voice stations aboard the International Space Station as well as other amateur radio satellites. Essentially, we try to ‘set the hook’ by giving students access to SWL experiences in the same way many of us got our start in amateur radio and with hands-on opportunity to download and analyze actual telemetry.

“A unique concept in designing the Youth Initiative program is that it is a community-based program available to all youth, through their own self-interest, though home-schooling and through programs such as Scouting, 4H or community based programs for youth with special needs. Teachers are welcome to incorporate the materials into their curriculum where their school boards allow them to do so. But, the key here is that school participation is not needed for parents or other leaders to utilize our materials.”

Karnauskas further explains that all materials are available online at no charge to every and all persons interested in furthering the interest of students in science, technology, engineering, art and mathematics.

AMSAT is grateful to Amateur Radio Digital Communications for a generous grant to cover the cost of software licenses for online development and for supplemental technical artwork.

Launch Teams Practiced Artemis 2 Countdown

In a prelude to the real deal, the four astronauts of the Artemis 2 mission boarded their Orion spacecraft inside the Vehicle Assembly Building at the Kennedy Space Center on Saturday afternoon, Dec. 20.

The three Americans and one Canadian participated in a launch day rehearsal referred to as the countdown demonstration test or CDDT. It was the first opportunity for everyone involved with the mission to be on hand and to go through the motions of the big day with the fully integrated rocket in the loop, instead of just data simulations. The test appeared to reach its conclusion with a cutoff of the simulated countdown at the T-29 seconds point at 5:51 p.m. EST (2251 UTC).

The rehearsal is already running at least a month behind schedule. It was scheduled for November 19 but NASA postponed that, eventually blaming “a blemish” on a thermal barrier surrounding the Orion crew access hatch which prevented its closure.

The test was rescheduled for Dec. 17, but that too was abruptly delayed without explanation.

The launch of Artemis 2 is currently slated for no earlier than February 6. NASA also says the launch will take place no later than April 2026.

Satellite Shorts From All Over

+ They weren’t home for Christmas, but astronauts in space found their own way to make the season bright. They’ve even hung their space stockings by the airlock with care. Four astronauts on the International Space Station (ISS) sent their best Christmas wishes to Earth as they orbit our planet. NASA astronauts Mike Fincke, Zena Cardman and Chris Williams and Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) sent a video Christmas card home as they and three other crewmates spend the holidays 250 miles (400 kilometers) above Earth. “Greetings to planet Earth, all of our friends and family, from Expedition 74 aboard the International Space Station, flying high above,” said Fincke, who commands the Expedition 74 crew on the ISS. “Thinking of you during this holiday season.” Watch the heartwarming greeting and feel the season bright at https://tinyurl.com/ANS-362-Greetings .

+ The global space sector is entering a phase of large-scale satellite constellations and expanded human lunar activity, driving a sharp increase in demand for access to orbit. Within the next two decades, the total mass launched to space is expected to reach several hundred thousand tons, with annual launch counts projected in the tens of thousands and continuing to grow. Launch providers therefore face simultaneous requirements for low cost, high flight rates, and airline-style reliability in space transportation systems. Reusable launch vehicles have reduced per-flight cost, but they do not yet deliver the launch tempo and reliability needed for this next phase of activity. A study in the Chinese Journal of Aeronautics argues that artificial intelligence applied across launch vehicle life cycles could address these remaining bottlenecks and become a disruptive technology following reusability in space transportation.The authors outline four main roles for AI in launch systems: agile test and launch preparation, high-reliability flight, rapid maintenance, and efficient safety operation and control.

Registration is open for the 2025–2026 European Astro Pi Challenge

Educators: Do you want to send your students’ computer programs to space with the European Astro Pi Challenge? Astro Pi Mission Zero and Mission Space Lab are now officially open for the 2025–2026 challenge.

Astro Pi is an ESA Education project run in collaboration with the Raspberry Pi Foundation and delivered nationally by the European Space Education Resource Offices (ESERO).

The project offers different levels of complexity:

Mission Zero – for beginners (up to 19 years old) to learn to write a simple program that will run in space. Mission Zero, well suited for beginners, offers a chance for young people to create a piece of pixel art and have it displayed for astronauts to see on two special Raspberry Pi computers, called Astro Pis, aboard the ISS. The deadline for Mission Zero submissions is 23 March 2026.

Mission Space Lab – for more experienced coders (up to 19 years old) to carry out a scientific task using a program that will run in space. For more experienced coders, Mission Space Lab returns with a real-world scientific task: calculate the speed of the ISS as accurately as possible using the Astro Pi’s sensors or camera. Teams of two to six young people need to write a Python program that collects data from the Astro Pi computers on the ISS to perform this calculation.

Every team that submits a program that complies with the official guidelines will be awarded a participation certificate.The submission deadline for Mission Space Lab is 16 February 2026.

What is Astro Pi?

The European Astro Pi Challenge, or Astro Pi for short, is a free educational project. It has two missions that young people up to 19 years old can participate in, depending on their programming abilities. Both missions use Python programming to create short computer programs that will be run on the International Space Station (ISS).

The Astro Pi school project platform offers educators a comprehensive suite of resources to engage students in space science and coding activities, as well as support and community engagement activities.

Optical Communications Systems Test the Limits of FCC Authority

As the U.S. regulator of non-Federal radio spectrum, the FCC has become one of the most important overseers of commercial space activity. No satellite system can realistically gain access to the U.S. market without prior FCC approval and oversight: the agency licenses space and Earth stations and coordinates U.S. filings with the International Telecommunication Union (ITU).

But optical communications systems—particularly optical ground stations—do not fit neatly within the FCC’s statutory authority to regulate communications by “wire or radio.” Optical transmissions are not “radio.” Rather, free-space optical communications, or “lasercoms,” use optical wavelengths—generally in the near-infrared portion of the spectrum—to transmit data between user terminals.

Traditionally, satellite communication systems have relied on radio frequency (RF) transmissions within designated spectrum bands to relay signals either between satellites or from satellites to Earth. While these systems remain reliable and widely used, RF spectrum has inherent limitations – most notably finite bandwidth, increasing congestion, and atmospheric attenuation.

Optical communications offer a different path. By transmitting optical wavelengths, typically in the near-infrared range, free-space optical links can provide much higher data rates than RF.

One key component is the optical ground station. Unlike a traditional RF ground station with a dish antenna, an optical ground station uses a telescope and optoelectronic components to transmit and receive laser signals.

Still, lasercom poses unique technical challenges. The same narrow beam that enhances security also imposes constraints: RF signals can blanket wide areas.

Atmosphere attenuation also remains a major challenge to lasercom: atmospheric attenuators such as dust, smoke, fog, haze, and inclement weather impair the technology’s ability to transmit information.

The FCC has long indicated that it does not have jurisdiction over optical inter-satellite links because they do not involve RF spectrum. If the FCC lacks authority over lasercom, it might be unable to apply licensing requirements, enforce technical standards, or impose other space access conditions such as orbital debris mitigation plans and post-mission disposal requirements.

Uncertainty also carries real risks – operators do not know whether FCC licensing will eventually be required, what conditions might apply, or whether or how the U.S. might ultimately coordinate internationally. Lack of clarity could also complicate global harmonization: other jurisdictions may set their own rules, creating inconsistent standards.

A Protocol Extension for GOLF Operations

At the recent AMSAT Space Symposium held in Phoenix, Arizona, AMSAT Software Engineer Heimir Thor Sverrisson, W1ANT/TF3ANT, presented on the protocol extension he has been developing for satellite command and control systems, focusing specifically on improvements needed for the GOLF satellite project. The existing setup, utilizing the AMCOM program, has been successfully operational since 2015, primarily employing straightforward commands such as those for transitioning the spacecraft into safe or health modes. However, the GOLF project necessitates a more complex command structure to handle longer payloads, especially those involving Automated Thermal Controls (ATCs), which require orbital parameters to be sent as a cohesive unit.

The discussion underlined the importance of maintaining the proven AMCOM infrastructure, proposing to leverage existing telemetry tools like FoxTelem. The proposal includes utilizing five bits of telemetry data to provide feedback on command status, thus ensuring that commands are transmitted successfully and effectively, addressing the limitations of the current system.

A pivotal part of the discussion revolved around the concept of “multipart commands.” Heimir illustrated a plan to modify the AMCOM command structure to allow the transmission of multiple segments in a single command, using a sequential numbering system to keep track of these packets. The extension would also involve designating specific bits to indicate whether a command is multipart and which piece of the command is being acknowledged or is missing.

Heimir elaborated on the technical elements of the transmission protocol, detailing how to manage packet loss and potential sequence issues via a robust acknowledgment system. The system would require two threads of execution at the ground station — one for sending commands and another for handling incoming telemetry. This dual threading is crucial as it allows for more efficient communications and processing, maintaining system integrity in the event of packet loss or transmission delays.

A key component of the protocol will be adjusting how command data is structured and transferred, with new formats proposed for command definitions. The transition from a CSV format to a more flexible and human-readable JSON format was suggested to accommodate the new capabilities, making it easier for engineering teams to integrate the changes into their workflows.

The presentation included a demonstration of a simulator designed to visually represent the command transmission process, showcasing how the protocol would function under various conditions, including different rates of packet loss. The simulator was created in Python and is hosted on Heimir’s GitHub repository, making it accessible for further exploration.

During the question and answer section, audience members raised concerns related to the security of satellite communications, particularly regarding potential cyber threats. Heimir reassured participants that encryption and digital signature protocols are already in place for uplink communications, although downlink encryption remains restricted by FCC regulations against obscured transmissions.

The meeting concluded with a reflection on the practicality and challenges of implementing these proposed changes, emphasizing the continuous need for advancements in satellite communication protocols to cater to growing operational complexities and security requirements. Follow-up actions were identified, including finalizing the simulation details and incorporating feedback from the engineering team into the command structure proposal. Thankful remarks were exchanged, acknowledging the collaborative efforts required for successful implementation.

REALOP CubeSat to Test Hard Drives for ADC System

The University of California, Davis will fly its REALOP 2U CubeSat mission with two goals in mind.

The primary goal of the mission will be to provide students with the educational opportunity to design, build, and test a satellite. Students will gain hands-on knowledge of the different subsystems of the satellite and they will learn about the use of amateur radio and how to use RF in order to communicate with spacecraft.

The secondary goal of the mission is to demonstrate the feasibility of using hard disk drives as a low cost alternative to reaction wheels for CubeSat attitude detection and control. This has the potential to reduce the financial barrier of entry into CubeSat development.

A UHF GMSK downlink with a 96 kHz symbol rate on 437.400 is proposed. Telemetry packets will use HDLC framing and a rate 1/2 convolutional forward error correction. Deployment from the ISS is planned for June 2026.

  • 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 .
