Fox-1A , AMSAT-OSCAR 85 or AO-85 is an American amateur radio satellite . It is a 1U Cubesat , was built by AMSAT -NA and carries a single-channel transponder for the U / V mode in FM radio. The satellite has a rod antenna for the 70 cm and 2 m bands . In order to enable a satellite launch as part of NASA's ELaNa program (Educational Launch of Nanosatellites) , the satellite continues to carry a student experiment ( MEMS - gyroscope ) from Pennsylvania State University.

According to the AMSAT-NA, Fox-1A serves as a replacement for OSCAR 51 . After a successful start, the satellite was assigned the OSCAR number 85.

mission

The satellite was launched on October 8, 2015 with an Atlas-5 (401) rocket together with the main payload Intruder 11A (NOSS-3 7A, USA 264, NROL 55) and twelve other Cubesat satellites from Vandenberg Air Force Base . After just a few hours, the transponder was put into operation, the first connections between amateur radio stations made and telemetry received.

After the satellite could not be picked up for a long time, the operator AMSAT North America declared the mission to be over on February 16, 2020. The cause is assumed to be a failure of the batteries.
