Fox-1Cliff, AO-95 or AMSAT OSCAR 95 is an American amateur radio satellite. Fox-1Cliff is a 1U CubeSat built by AMSAT-NA that carries a single-channel transponder for mode U/V in FM.[1]
The satellite carries several student experiments:[2]
- Vanderbilt University Low Energy Proton (LEP) radiation experiment (flight spare from Fox-1A)
- Penn State University Erie gyroscope experiment
It also carries a VGA camera provided by Virginia Tech.
Mission

Fox-1Cliff was launched on 3 December, 2018 via Falcon 9 Block 5 from Vandenberg Air Force Base, California, United States.[3]
Receiver failure
Shortly after deployment, AO-95's receiver suffered a failure due to unknown reasons.[4]
Name
The satellite is the third of five Fox-1 satellites, and was originally named Fox-1C. In 2016, it was renamed Fox-1Cliff in honor of Cliff Buttschardt, a long time member of AMSAT and a contributor to the project, who died earlier that year.[5] After its launch, Fox-1Cliff was renamed AO-95.
