Fox-1A

Fox-1A, AO-85 or AMSAT OSCAR 85[3] is an American amateur radio satellite. It is a 1U Cubesat, was built by the AMSAT-NA and carries a single-channel transponder for FM radio. The satellite has one rod antenna each for the 70 centimetres (28 in) and 2 metres (6 ft 7 in) bands. To enable a satellite launch under NASA's Educational Launch of Nanosatellites (ELaNa) program, the satellite continues to carry a Penn State University student experiment (MEMS gyroscope).

According to AMSAT-NA, Fox-1A will replace OSCAR 51. Upon successful launch, the satellite was assigned OSCAR number 85.

Launch and mission

The satellite was launched on 8 October 2015 with an Atlas V rocket together with the main payload Intruder 11A (also known as NOSS-3 7A, USA 264 and NROL 55) and 12 other Cubesat satellites (SNaP-3 ALICE, SNaP-3 EDDIE, SNaP-3 JIMI, LMRSTSat, SINOD-D 1, SINOD-D 3, AeroCube 5C, OCSD A, ARC 1, BisonSat, PropCube 1 and PropCube 3) from Vandenberg Air Force Base, California, United States. After just a few hours, the transponder was put into operation, initial connections were made between amateur radio stations and telemetry was received.
