Sounds from Amateur Radio Satellites 2023-today

 

This section is dedicated to satellites built and operated by Radio Amateurs. Satellites built by AMSAT organizations around the world and were called AMSAT-OSCAR. Those built by Russian Hams and were mostly called Radiosputnik. In order to build and launch the satellites AMSAT needs members and friends to contribute and raise funds. If you are not yet a member of AMSAT please consider to join us and to support the activities. You can find several links to AMSAT on my links page.

 #56992
(2023-084bu)

URESAT-1 is a 1.5P PocketQube (8x5x5 cm) picosatellite developed by AMSAT EA. HADES-B was launched with SpaceX on June 12th 2023 (Transporter-8 mission from Vanderberg).

The satellite was expelled from the D-Orbit Orbital Transfer Vehicle (OTV) ION ten days after the launch, on June 22nd at 12.10 UTC, along with MRC-100 and ROM-2 satellites. Unfortunately the satellte had a problem with the deployment of the antennas and thus only stations ith larger antennas were able to receive its downlink (telemetry, CW and SSTV).

It is a mission which offers radio-amateurs around the world the opportunity to relay FM voice and AX.25 / APRS 300/1200 bps communications. This is achieved by implementing a SDR based FM and FSK repeater. A SSTV camera module by Brno University is expected to fly depending on time restrictions. Images would be taken in a random way. The SSTV module would contain some ROM coded images to be transmitted as well. URESAT hardware and software subsystems are enhanced ones of the previous AMSAT-EA HADES.

SO-121
Spain-OSCAR 121
HADES-D

 #58567
(2023-174cy)

HADES-D was launched into space on the SpaceX TR-9 mission dated November 11, remaining in orbit inside the orbital transfer vehicle (OTV) ION-SCV-013 from D-ORBIT until the 18th when said 'mother satellite' ejected it, at 7:53 UTC.

The repeater works with FM/FSK (MSK144 has been tested too) with an uplink frequency of 145,875 MHz and a downlink frequency of 436.6635 MHz (a bit lower than the 436.666 MHz expected). We have been able to verify that the modulation is more appropriate by narrowing the bandwidth, so it is recommended to use NFM in those devices allowing it.

HADES-D is the first satellite with FM repeater service mounted on a pocketqube platform. This standard is the smallest in terms of normalized satellite sizes. HADES-D size is 8x5x5 cm. Its panel surface and battery size are much smaller than the rest of the satellite repeaters in use, so HADES-D is not comparable to most of them either in radiated power or signal strength. HADES-D should be considered a QRP satellite.
