OSCAR 44 (also calledNavy-OSCAR 44,PCSat-1,Prototype Communications SATellite andNO-44) is an Americanamateur radiosatellite for packet radio. It was built byBob Bruninga at theU.S. Naval Academy.
The satellite was launched on September 30, 2001 by theKodiak Launch Complex,Alaska, using anAthena 1 rocket along with theStarshine 3,PICOSat andSAPPHIRE satellites. After the successful launch, the satellite was assignedOSCAR number 44.
The satellite has adigipeater for APRS in the 2-meter band. OSCAR 44 usually works with a negative power balance, which means that it is supplied with voltage by the photovoltaic cells each time it enters sunlight and remains active for another 45 minutes when it leaves sunlight using the battery charged by thephotovoltaic cells.[3]
