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.
