Fox-1B,AO-91 orAMSAT OSCAR 91[3] is aUnited Statesamateur radio satellite. It is a 1UCubesat, was built by theAMSAT-NA and carries a single-channel transponder forFMradio. The satellite has a whip antenna for the 70 cm and 23 cm bands (uplink), and a second antenna for the 2 m band (downlink). Fox-1B is the second amateur radio satellite of the Fox series ofAMSAT North America.
To facilitate a satellite launch as part ofNASA'sEducational Launch of Nanosatellites (ELaNa) program, the satellite carries a student experiment conducted byVanderbilt University's Institute for Space and Defense Electronics. The RadFx experiment at this institute hosts four payloads for the study ofradiation effects on commercially available electronic components. So it should be testedelectronic components "off the shelf" under space conditions. The payload of AMSAT North America is a single-channel FM converter fromUltra high frequency (UHF) toVery high frequency (VHF). After successful launch, the satellite was assigned the OSCAR number 91.
The satellite was launched on 18 November 2017, with aDelta IIlaunch vehicle, along with the main payloadJoint Polar Satellite System (JPSS)NOAA-20 and 4 other Cubesat satellites (MiRaTA,Buccaneer RMM,EagleSat andMakerSat 0) fromVandenberg Air Force Base. After only a few hours, telemetry was received and thetransponder put into operation.
