AMSAT-EA satellites to launch

GENESIS-J and GENESIS-G satellites

GENESIS-J and GENESIS-G satellites

Felix EA4GQS reports Spain’s latest amateur radio satellites to launch will be GENESIS-G and GENESIS-J on September 11

The AMSAT Bulletin Board post says:

This is to confirm that the launch of our new GENESIS-G and GENESIS-J satellites with Firefly will take place, if all goes well, on September 11, with the launch window starting at 3 PM Pacific Time (22h GMT), from Vanderberg. The expected orbit altitude is 300 km with an inclination of 137 degrees.

As many of you know, this will be the second attempt of Firefly to reach orbit after the first attempt made in September 2021 and which had to be aborted after two minutes of flight, causing our previous GENESIS-N and GENESIS-L to be lost, among others.

These new GENESIS have a more powerful on-board computer than their predecessors and updated software that allows FM voice repeater functionality, AFSK/FSK non-regenerative repeater up to 2400 bps, FSK regenerative repeater up to 50 bps, CW, digitized voice pre-recorded FM and FSK telemetry at 50 bps. The correct retransmission of AX25 / APRS frames over FM up to 2400 bps has been verified in the laboratory.

A small drawback we still have is the antenna deployment mechanism, that is the first version that was made and requires a plenty charged battery. The satellites have been stored for several months, so it is a weak point. Hopefully it will work.

These satellites also have the names of ASTROLAND-1 and ASTROLAND-2 to say thanks to the sponsorship of the project by the Astroland Planetary Agency. We also thank the private companies and Universities that helped in the project.

As on the previous occasion, two experimental propellants are flown, although this time they are from the Madrid company IENAI Space and, unlike the previous GENESIS mission, they use a liquid ionic fuel. Only the one from GENESIS-J is functional. The one from GENESIS-G carries the electronics but without the fuel.

The frequencies coordinated with IARU are the following:

145.875 MHz uplink, Modes: FM voice (no subtone) and FSK 50 bps, AFSK, AX.25, APRS 1200 / 2400 bps
436.888 MHz downlink, Modes: FM voice, CW, FSK 50 bps, FM voice beacon with AM2SAT callsign

145.925 MHz uplink, Modes: FM voice (no subtone) and FSK 50 bps, AFSK, AX.25, APRS 1200 / 2400 bps
436.666 MHz downlink, Modes: FM voice, CW FSK 50 bps, SSTV Robot 36, FM voice beacon with AM3SAT callsign

We encourage all of you to try to receive their first transmissions once the first keplerians are available.

This flight will be streamed by Everyday Astronaut:

GENESIS satellites to launch



After a year waiting, finally this Friday, September 3, at 01:00 UTC the digital GENESIS satellites are expected to launch from Vanderberg AFB aboard Firefly’s Alpha rocket in its maiden flight.

Update Sept 3. 2021: A flight anomaly resulted in the loss of the satellites.

Felix Paez EA4GQS reports:
“Unfortunately, the GENESIS satellites were destroyed along with the Firefly Alpha vehicle as it suffered an anomaly when it was travelling at Mach 1 speed about two minutes after the launch. It was Firefly’s first flight and it was the second attempt after the first had been aborted an hour earlier a few seconds before takeoff.

We are very proud of all the team work and very grateful for this opportunity Firefly has granted to us.

In January we will launch with SpaceX through Alba Orbital, our FM repeaters Hades and EASAT-2. We will keep you posted.”

These satellites are ASK (OOK) and CW repeaters. They transmit a lot of telemetry and also 19 different CW greeting messages in English and Spanish.

We would like to ask you all to please try to receive them as any information about their transmissions would be very valuable for us. These are the first satellites we build by ourselves and we need to learn everything we can of them. Waterfalls, audio USB receptions or IQ files would be very appreciated. Please send them to or to We will send you a nice QSL.

Initial keplerians are listed below. We expect to provide accurate ones a pair of days after the launch.

AMSAT-EA GENESIS satellites may launch September



Spain’s national amateur radio society, the URE, report two AMSAT-EA GENESIS satellites are expected to be launched on September 2, 2021.

A translation of the URE post reads:

The GENESIS-L and GENESIS-N satellites, designed and built by AMSAT-EA in collaboration with students from the European University and ICAI, will be launched, in a first attempt, on September 2, once the American company Firefly has carried out the static test of the Alpha launcher, this being the last step before its launch. The vehicle is ready for takeoff on its platform from Vanderberg Air Force Base in California and carries, for this inaugural flight, many other satellites from various organizations and universities.

The GENESIS are digital repeating satellites of ASK and CW and also carry Applied Ion Systems’ AIS-gPPT3-1C experimental ion thrusters.

The working frequencies of the satellites are as follows:

145.875 MHz uplink, Modes: CW, ASK 50 bps
436.875 MHz downlink CW, ASK 50 bps, am2sat callsign

145.888 MHz uplink, Modes: CW and ASK 50 bps
436.888 MHz downlink CW ASK 50 bps, am3sat callsign

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.
