MIR-SAT1 to deploy from ISS

MIR-SAT1 CubeSat

MIR-SAT1 CubeSat

The Mauritius Amateur Radio Society (MARS), is offering an Award to commemorate the deployment of the MIR-SAT1 CubeSat from the ISS, planned for June 22 at 10:55 GMT.

The award is open to all participating Radio Amateurs/SWLs worldwide and will be issued to those decoding MIR-SAT1 telemetry (TLM) and forwarding it to SatNogs.

Full details of the award and links to telemetry decoders are at
https://mars3b8.wordpress.com/2021/06/19/mir-sat1-special-award/

The deployment will be shown live on JAXA YouTube channel, the broadcast starts at 10:35 GMT on Tuesday, June 22.

The IARU Satellite Frequency Coordination page reports:

MIR-SAT1 is a 1U CubeSat mission with the following objectives:

1. Verify the performance of the on-board subsystems by receiving telemetry from the satellite and establish communication to and from the satellite (command and control).
2. Collect images of Mauritius and the Mauritian EEZ for capacity, building, experiment and research.
3. Experimental communication with other islands via the satellite (for scientific and/or emergency purposes), through a Radio Amateur digipeater payload.
4. V/U 9600bps GMSK digipeater may be open for Radio Amateur communication worldwide when the satellite not used for all above.

A downlink on 436.925 MHz has been coordinated. Decoders for the amateur radio community and schools have been developed by Chris AC2CZ and Daniel EA4GPZ and will be available in the public domain on their WEB sites/Github, Links will be provided before launch on Tweeter, AMSAT-BB and Space Mauritius, see

For the digipeater operation it will be necessary to evaluate the power available after deployment to decide on opening same 24/7 or on scheduled time.

CHESS will not have an amateur payload

Two CHESS CubeSats had been planned to carry amateur radio linear transponders, however, it was announced on June 10, 2021, there will not be any amateur payload on the satellites.

A translation of the press release reads:

The CHESS project management, due to funding constraints, had to move the project towards a commercial cubesat platform. Space is scarce on this new platform to accommodate another payload. Subsequently, there is no longer an opportunity to carry a ham radio transponder on board.

The CHESS project management has correctly decided not to use frequencies in the amateur satellite service and to use earth exploration or experimental UHF- and X- band frequencies.

The ham community, who assured the funding of the transponder, is very disappointed by this decision, but must accept it.

Such projects always carry risks of one partner changing its mind. That is what happened here.

Many thanks to all who have actively supported the transponder project, especially the AMSAT-UK and AMSAT-NL team.

EASAT-2 and Hades launch delayed again

Spain’s URE reports the launch of EASAT-2 and Hades satellites have suffered another delay.

A translation of the URE post reads:

EASAT-2 and Hades, the communications satellites for radio amateurs built by AMSAT-EA, will not be able to be launched in June with SpaceX as planned, as the FAA (the American Aviation Administration) has rejected the license to the integrator Momentus Space, On whose orbital transfer vehicle Vigoride was to be mounted the AlbaPOD ejector from Alba Orbital, within which are the satellites of AMSAT EA, as well as other organizations and universities.

The reasons for the FAA’s rejection stem from the company’s capital structure, which, according to the American agency, could endanger the national security of the United States. The next launch opportunity could come in December.

EASAT-2 and Hades were to have been launched in January this year aboard a SpaceX Falcon-9 rocket, but the Momentus license was also rejected by the FAA at the time.

Both satellites are FM and FSK voice repeaters, also having digitized voice recordings. Hades also incorporates an SSTV camera developed by the University of Brno in the Czech Republic and EASAT-2 incorporates as an experimental load a basaltic material from Lanzarote, similar to lunar basalts, provided by the research group on meteorites and planetary geosciences of the CSIC in the Institute of Geosciences, IGEO (CSIC-UCM) and that it could be used as a construction material on the Moon. This project was promoted and has the collaboration of the ETSICCP (UPM).

The frequencies coordinated with the IARU for both satellites are the following:

EASAT-2
• 145.875 MHz uplink, Modes: FM voice (without sub-tone) and FSK 50 bps
• 436.666 MHz downlink, Modes: FM voice, CW, FSK 50 bps, FM voice beacon with AM5SAT callsign

HADES
• 145.925 MHz uplink, Modes: FM voice (without sub-tone) and FSK 50 bps
• 436.888 MHz downlink, Modes: FM voice, CW FSK 50 bps, SSTV Robot 36, FM voice beacon with callsign AM6SAT

Radio amateur G3YJO on BBC Radio 4

Professor Sir Martin Sweeting G3YJO

Professor Sir Martin Sweeting G3YJO

Radio amateur Professor Sir Martin Sweeting G3YJO, was the guest on the Radio 4 show The Life Scientific that was broadcast on Tuesday, April 20.

Martin Sweeting G3YJO pioneered the original SmallSats revolutions with the UOSAT-1 and UOSAT-2 spacecraft that carried amateur radio payloads and launched in the early 1980’s. They led to the founding of Surrey Satellite Technology Ltd (SSTL) of which he is Executive Chairman.

More than a million UVQSat telemetry frames received

AMSAT-Francophone Logo

AMSAT-F have issued an update on the UVQSat CubeSat, they plan to conduct further test on the FM transponder.

In a post to the AMSAT Bulletin Board the AMSAT-F President Christophe Mercier says:

More than 1,200,000 frames have been received on the AMSAT-F experimental database this week https://amsat.electrolab.fr/

It is possible to visualize the data via an online Dashboard:
https://amsat.electrolab.fr/grafana/d/ujwd-SaMz/uvsqsat?orgId=1

These data were collected by more than 50 stations in the world via the UVSQsat decoder software. The software allows to send the data to the AMSAT-F and Satnogs databases. The continuous reception of telemetry is valuable to the project team that is piloting the satellite.

Although the downloading of large amounts of data is done over Europe, this also took place over Japan with the help of Japanese radio amateurs.

It is noted that a new version of the UVSQSAT Decoder software is available with new features (new ASCII telemetry decoded, performance improvement,..)

The commissioning phase has been successfully completed. Now the UVSQsat project team with Radioclub F6KRK and AMSAT-Francophone will conduct further tests on the transponder to ensure that it can be operated over a period of several days without taking any risk to the satellite.

For this we are looking for volunteer radio amateurs to participate in these tests on all continents. If you are interested contact AMSAT-Francophone, email amsatf<at>amsat-f.org
