ParkinsonSAT,PSat orNaval Academy OSCAR 84 is aU.S.technology demonstrationsatellite and anamateur radio satellite for Packet Radio. It was built at theU.S. Naval Academy and was planned as a double satellite (ParkinsonSAT A and B). The name ParkinsonSAT was chosen in honor ofBradford Parkinson, the father of theGPS system. After successful launch, the satellite was assigned theOSCAR number 84.
The satellite was launched on May 20, 2015, with anAtlas V rocket along with the main payload X-37B OTV-4 and 9 other CubeSat satellites (X-37B OTV-4,GEARRS 2,LightSail A,OptiCube 1,OptiCube 2,OptiCube 3,USS Langley,AeroCube 8A,AeroCube 8B andBRICSat-P) fromCape Canaveral AFS,Florida.
ParkinsonSAT is a student satellite project. It was partly funded by theAerospace Corporation. It has atransponder for transmittingtelemetry from remote measuring points (eg drifting buoys). This telemetry is to be transmitted to a network of ground stations. A second transponder enables multi-user text transmission in PSK31 mode. This transponder was built by theBrno University of Technology.[3]
Originally, the project consisted of 2 identical satellites: PSat-A and PSat-B, 2 identical 1.5U Cubesats, which should be brought together in a 3U starter into space. During the long wait for a launch opportunity in 2014, the construction of the satellite was changed again. Thesolar cells have been replaced by new, more efficient cells. The other originally named PSat-B CubeSat was rebuilt and started as BRICSat-P.
