PSAT-2 is an experimental amateur radio satellite from the U.S. Naval Academy, which was developed in collaboration with the Technical University of Brno in Brno, Czech Republic. AMSAT North America's OSCAR number administrator assigned number 104 to this satellite; in the amateur radio community it is therefore also called Navy-OSCAR 104, short NO-104.
Mission
[edit | edit source]PSAT-2 was launched on June 25, 2019 with a Falcon Heavy from Kennedy Space Center, Florida, United States, as part of Mission STP-2 (Space Test Program 2) as one of 24 satellites. In August 2019, the VHF payload failed and control of the satellite was lost. However, after nearly two years of downtime, the payload mysteriously reactivated and control was regained.
Frequencies
[edit | edit source]The following frequencies for the satellite were coordinated by the International Amateur Radio Union:
- 145.825 MHz - Uplink and downlink APRS digipeater, 1200 bd (once again functional as of 2021)
- 435.350 MHz - Downlink PSK31 and SSTV
- 29.4815 MHz - Uplink PSK31
