It is a 1U Cubesat, was built by the AMSAT-NA and carries a single-channel transponder for FM radio. The satellite has a whip antenna for the 70cm and 23cm bands (uplink), and a second antenna for the 2m band (downlink). Fox-1B is the second amateur radio satellite of the Fox series of AMSAT North America. To facilitate a satellite launch as part of NASA's Educational Launch of Nanosatellites (ELaNa) program, the satellite carries a student experiment conducted by Vanderbilt University's Institute for Space and Defense Electronics. The RadFx experiment at this institute hosts four payloads for the study of radiation effects on commercially available electronic components. So it should be tested electronic components "off the shelf" under space conditions. The payload of AMSAT North America is a single-channel FM converter from UHF to VHF. After successful launch, the satellite was assigned the OSCAR number 91. MissionThe satellite was launched on November 18, 2017, with a Delta II rocket, along with the main payload Joint Polar Satellite System and 4 other Cubesat satellites (MiRaTA, Buccaneer RMM, EagleSat and MakerSat 0) from Vandenberg Air Force Base. After only a few hours, telemetry was received and the transponder put into operation.
