PSAT-2 is an experimentalamateur radio satellite from theU.S. Naval Academy, which was developed in collaboration with theTechnical University of Brno inBrno,Czech Republic.AMSAT North America's OSCAR number administrator assigned number 104 to this satellite; in the amateur radio community it is therefore also calledNavy-OSCAR 104, shortNO-104.
PSAT-2 was launched on June 25, 2019 with aFalcon Heavy fromKennedy Space Center,Florida, United States, as part of MissionSTP-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.
The following frequencies for the satellite were coordinated by theInternational Amateur Radio Union:
