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.

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

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.

The October 2025 rankings for the Top 100 Rovers (Mixed LEO/MEO/GEO) in satellite operations, as determined by @GridMasterMap on Twitter, has been released. The ranking is determined by the number of grids and DXCC entities activated, taking into account only those grids where a minimum number of QSOs logged on the gridmaster.fr website have been validated by a third party. Grid numbers do not directly reflect the exact number of activations. Satellite operators are encouraged to upload their LoTW satellite contacts to https://gridmaster.fr in order to provide more accurate data.

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.

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/ . [ANS thanks Tom Schuessler, N5HYP for the above information.]
• 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.

• 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.

Bankston Introduces 2025 Hamvention AMSAT Forum

AMSAT President Robert Bankston greeted attendees of the Hamvention Saturday, May 17, 2025 AMSAT Forum, kicking off the session which included short presentations by several AMSAT Engineering leaders.

Bankston explained that the organization was officially formed in 1969 saying, “We’ve been keeping Amateur Radio in space for more than 50 years starting with OSCAR 1 in 1961.” OSCAR-1 was launched on December 12, 1961 as a secondary payload on the Thor-Agena rocket with a US Air Force mission. OSCAR-1 was the first satellite ever to be deployed as a secondary payload from a launch vehicle.

“The bureaucratic efforts required to secure permission to launch OSCAR-1 greatly exceeded the effort required to build the satellite. It established the precedent for all subsequent secondary payload launches for the next five decades.”

“Speaking of the fun of being a part of AMSAT,” Bankston said, “Our primary goal is to have Amateur Radio available in space for you to operate with. And if you haven’t done it before, it’s a blast. You’re chasing that little chunk of radio, flying through space at 17,000 miles an hour and trying to keep up with it, whether it be by hand or with automated azimuth and elevation tracking antennas. Accomplishing that is great stuff.”

Bankston told the audience that even more than operating via satellite communications, many AMSAT members get the opportunity to design and build a satellite that goes up into space. “AMSAT has a lot to offer to everybody. We are looking forward to enhanced relationships with school-aged students and their teachers via our new Youth Initiative which includes online self-learning.

“Currently AMSAT has about 4,000 members, the majority of whom are in the United States. AMSAT members also are in some 53 countries. There are other AMSAT organizations around the world, in such countries as the UK, Spain, Germany, Japan, Brazil and many others.

“AMSAT shares a strategic relationship with the U.S. Amateur Radio on the International Space Station (ARISS) organization. That group facilitates worldwide space-oriented education programs primarily in middle and high schools. Student activities in the ARISS program culminate with a capstone of a live question and answer session via Amateur Radio with an astronaut aboard the International Space Station (ISS). More than 100 astronauts have obtained and use an Amateur Radio license issued by their home country to legally transmit via radios installed on the ISS.”

The forum session provided an update on current activities. Bankston said, “the most important part of today’s update is what our AMSAT engineers are working on.” The lineup of engineering professionals who presented talks began with Jerry Buxton, AMSAT VP of Engineering and his team. Buxton spoke about the importance of AMSAT’s volunteer engineers and an overview of current AMSAT projects.

Burns Fisher – The Legacy of AMSAT Flight Software

Note; Burns Fisher, WB1FJ, AMSAT Senior Software Engineer spoke at the 2025 Hamvention AMSAT Forum about his involvement in the development of flight software for AMSAT satellites and progress to date. His non-technical presentation helped attendees understand the scope of AMSAT software advancements during the past 15 years. This is Par 1 of a 2 Part series.

“I began working on Fox-1 software during 2010. The Fox-1 series of cubesats progressed from A through B, C, D and E. Software for each new satellite is based on that original Fox-1A software, including the five FOX-1 satellites as well as those flown by University of Washington and University of Maine. This is because we make AMSAT radios and processors available to universities so our software is used to control the AMSAT boards.

“Fox-1A was launched in 2015. Since then we’ve refined, added to and reused the same fundamental programs, although each satellite features different capabilities and many other individual program refinements. Specific variations include satellite bus data configurations connecting new subsystems or improved modules within the flight computer. We almost always discover a few bugs in the current satellite which we try to fix in the next one.

“Commands transmitted from a ground station control the Amateur Radio repeater or transponder receive and transmit functions as well as other satellite functions. These commands use encryption to securely authenticate that commands are coming from an AMSAT ground station. Controlling devices like satellites is the only time that encryption is allowed in Amateur Radio.

“In addition, the flight software collects telemetry data from various systems in the satellite, combines it and transmits it back to earth so we can read and use the data to monitor our satellites and the investigators who provided science experiments can get their results.”

“FoxTelem Software for Windows, Mac, and Linux platforms can demodulate, store and analyze telemetry signals from AMSAT cubesats. FoxTelem users, who do not have to be licensed amateurs can upload received telemetry data to the AMSAT server so that it can be used by scientists and researchers whose experiments fly AMSAT satellites as well as by AMSAT engineers monitoring the health of the spacecraft.” (More details or download here: https://www.amsat.org/foxtelem-software-for-windows-mac-linux/)

Burns continued, “If you want to know what the flight software does, the easiest way to see this is to look at the tasks within it. You can think of tasks as being like applications on your phone. This chart shows the list of current flight software tasks.

“One flight task example is a diagnostic task for debugging and testing systems on the bench. Another software task controls experiments such as the Vanderbilt University radiation experiment and the Virginia Tech camera.

The yellow boxes represent two new tasks coordinating multiple processors, and controlling a new electrical bus called CAN. GOLF flight software is still based on the original Fox-1 software but is more complicated and required an enormous amount of additional programming.

“GOLF satellites have a Controller Area Network bus (CAN bus) designed to enable efficient communication between processors and other devices. The CAN bus concept originated in the Automotive Industry to connect automotive ECUs (Electronic Control Units). Its purpose is to reduce the complexity and cost of electrical wiring in automobiles by multiplexing different kinds of data. Multiplexing combines multiple input signals into a single output signal for transmission over a shared channel. There are multiple processors on GOLF.”

While Fox satellites are all in Low Earth Orbits between approximately 500 km and 800 km altitudes, Burns needs to test newly added functions required for navigation and propulsion, part of AMSAT’s strategic goals involving highly elliptical orbits for wide access satellite missions.

(Note: Part 2 of this series will appear in next week’s ANS Weekly Bulletin.)

SkyRoof – A Specialized Satellite Tracking Program for SDR’s

SkyRoof , developed by Alex Shovkoplyas, VE3NEA, is a satellite tracking and radio control program that focuses on software design radio (SDR) operation. The program supports SDR-based SSB/CW/FM receivers with RIT and Doppler tracking. Frequency tuning is done visually with a mouse.

It provides detailed information about all satellites that transmit in the ham bands while all satellite traces on the waterfall are labeled with satellite names, and the boundaries of the transponder segments. 

SkyRoof provides the usual pass prediction for selected satellites and visual representation of the current satellite position and future passes in several formats including Sky View – the view of the sky from your location; Earth View – the view of the Earth from the satellite; Time Line – the satellite passes on the time scale; and Pass List – the details of the predicted passes. The SDR-based waterfall display covers the whole satellite segments on the VHF and UHF bands, with zoom and pan.

The program supplies audio and I/Q output to external programs via a virtual audio cable (VAC). CAT control of an external transceiver is also said to be provided along with antenna rotator control.

SkyRoof is currently available only for MS Windows. It is open source and can be downloaded for free at https://ve3nea.github.io/SkyRoof/index.html.

Changes to AMSAT-NA TLE Distribution for June 13, 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/.

Satellite Shorts From All Over

• • From September 19-21, 2025, the Bochum radome will once again be dedicated to satellite and space research. In cooperation with the Bochum Observatory, AMSAT-Deutschland e.V. is offering a varied and informative program aimed at AMSAT members and all space enthusiasts. The focus is on current developments and future prospects for national and international amateur radio satellites and other space projects. Lectures, presentations and exciting discussions will provide participants with valuable insights into the latest technologies, missions and research projects in space travel. As was the case last year, the Space Days begin on Friday with a general “come together” and end on Sunday with the General Assembly. The exact schedule and further plans here on the website as soon as possible. Anyone interested in giving a presentation is welcome to contact them in advance at [email protected].

• • The SpaceX launch of four private astronauts has been delayed again. The Axiom Space’s Axiom Mission 4 (Ax-4) mission to the International Space Station (ISS) had been scheduled to launch atop a SpaceX Falcon 9 rocket from Florida’s Space Coast on Wednesday morning, June 11, but a propellant leak in the Falcon 9 booster nixed that plan. And now, another leak — this one in a leaky module at Ax-4’s destination, the ISS — has further postponed the liftoff indefinitely. This is the first flight for the Dragon spacecraft supporting this mission. This will be the second flight for the first stage booster supporting this mission, which previously launched a Starlink mission. [ANS thanks SpaceX.com for the above information.]
