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

URE satellite telecommand station automated

AMSAT-EA Hades PocketQube

AMSAT-EA Hades PocketQube

Spain’s national amateur radio society URE has announced their satellite ground station has been automated and is ready for the launch of GENESIS, EASAT-2 and Hades satellites.

A translation of the URE post reads:

The URE satellite monitoring and telecommand station, located at the Madrid headquarters, on Monte Igueldo street, has recently been completely automated, thanks to the efforts made in recent weeks.

These works, which began to be carried out before the confinements due to the pandemic, have consisted of the change of the lifting rotor, which due to its long time without maintenance had been unusable, the alignment of the antennas, both VHF and UHF, of circular polarization, the installation of a Linux computer, the configuration of the reception software with SDR and the emission software using Pluto hardware, acquired by URE, as well as the automation of the rotor control with the hardware provided by EA4TX (ARS).

This station will automatically record and analyze the telemetry of the twin GÉNESIS satellites, as well as EASAT-2 and Hades, all of them designed and built by AMSAT EA, as well as remote control in the event that actions are necessary on your computer from a on board, which, once in space, will be able to receive instructions from Earth to modify its operation, although the satellites themselves implement the intelligence necessary to adapt to adverse circumstances that may occur in space.

The GENESIS satellites should be launched soon, once Firefly, the American company that built the launch vehicle, completes the static tests of its Alpha rocket, which is already prepared at the Vanderberg space base in California. As for Hades and EASAT-2, both are currently at the Momentus space integrator facilities in Santa Clara, also in California, and it is expected that they can be launched aboard SpaceX’s Falcon-9 rocket in late June from Cape Canaveral, once, overcome the problems of the Momentus company, which prevented its scheduled launch in January of this year.

GB2RS News available on QO-100 satellite from this Sunday

Es'hail-2 Qatar-OSCAR-100The RSGB has announced that their popular weekly GB2RS news broadcast will now be available via the QO-100 amateur radio transponder on the geostationary satellite Es’hail-2.

QO-100 provides continuous coverage from eastern Brazil to as far west as Thailand. There are two amateur transponders, one for Narrowband modes such as SSB and FT8 and the other for digital amateur television (DATV).

The RSGB website says:

“GB2RS can now also be heard via the QO-100 amateur radio satellite. The transmission is provided by Keith, GU6EFB at 0800UTC, using upper sideband on 10489.900 MHz, which is in the mixed-mode section of the narrowband transponder. QO-100 is a geostationary satellite with a footprint that covers Europe, Africa and India, so this news bulletin is a specially-adapted international version. The RSGB would like to thank AMSAT-DL for their kind cooperation in making this broadcast possible.”

If you do not have 10 GHz receive capability you can still listen to the broadcast on the AMSAT-UK and BATC WebSDR located at Goonhilly, see

Recent activity on the 23cm band RNSS Coexistence Studies

CEPT LogoThe Chair of IARU Region 1 Spectrum Affairs, Barry Lewis G4SJH, reports on the work being done in defending the interests of the Amateur Services in the 1240-1300 MHz band.

His IARU Region 1 post reads:

IARU is continuing to represent the amateur services interests in the 23cm band Galileo/GLONASS radio navigation satellite service coexistence discussions in the CEPT project teams.

The most recent CEPT SE40 project team meeting was held from 24th to 26th March 2021 and the IARU R1 was represented by Barry Lewis, G4SJH (Region 1 SRLC chair). At that meeting the first coexistence calculations were introduced by one CEPT administration, based on some initial assumptions about the amateur service operation. The IARU is continuing to work with the regulators to refine the details of these assumptions and make them and the calculations more representative of typical amateur station characteristics and band usage. These first calculations are considered only as a starting point and the meeting agreed that further work is needed to develop the calculations into a more comprehensive study.

Measurement campaigns have shown that the potential for coexistence depends very much on the frequency of the amateur service transmissions in the 23cm band with respect to the RNSS receiver bandwidth. This aspect needs to be considered more carefully once the initial scenarios and calculations are agreed.

In addition the IARU continues to have questions about the protection criteria required by the RNSS receivers and in particular how they relate to RNSS operational and service provision behaviour. IARU has ensured alignment of the amateur and amateur service information being used in CEPT with that being used in the parallel work in the ITU‑R relating to WRC-23 AI 9.1b.

At the RSGB AGM held on Saturday, April 24, 2021 the Society awarded the Louis Varney Cup for advances in space communications to Dave Crump G8GKQ.

Dave accepts this award as Chair of the British Amateur Television Club. His leadership of the BATC community, both in the UK and overseas, has been instrumental in enabling the QO100 satellite wideband transponder to be fully utilized with many new DATV systems being developed since the launch of the spacecraft.

This award acknowledges the exciting and significant contributions made by many members of the BATC, both in terms of software and hardware.

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.
