ParkinsonSAT, PSat or Naval Academy OSCAR 84 is a U.S. technology demonstration satellite and an amateur radio satellite for Packet Radio. It was built at the U.S. Naval Academy and was planned as a double satellite (ParkinsonSAT A and B). The name ParkinsonSAT was chosen in honor of Bradford Parkinson, the father of the GPS system. After successful launch, the satellite was assigned the OSCAR number 84.

Mission

[edit]

The satellite was launched on May 20, 2015, with an Atlas 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 and BRICSat-P) from Cape Canaveral AFS, Florida.

ParkinsonSAT is a student satellite project. It was partly funded by the Aerospace Corporation. It has a transponder for transmitting telemetry 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 the Brno 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. The solar cells have been replaced by new, more efficient cells. The other originally named PSat-B CubeSat was rebuilt and started as BRICSat-P.
