Fox-1Cliff , AO-95 or AMSAT OSCAR 95 is an American amateur radio satellite . Fox-1Cliff is a 1U CubeSat that was developed and built by AMSAT-NA . The satellite is named Cliff in honor of Cliff Buttschardt, K7RR ex-W6HDO (1931-2006), a pioneer of the American AMSAT. After a successful start, the satellite was assigned the OSCAR number 95.

construction

Fox-1Cliff carries a single-channel transponder for the U / V mode in FM . Fox-1Cliff has an L-band converter (the AMSAT L-band downshifter experiment), which enables the FM transponder to be switched on an uplink in the 23 cm band .

The satellite carries the following scientific and technical payloads:

  • U / V FM repeater (identical to Fox-1A ).
  • L-band downshifter.
  • the Vanderbilt Low Energy Proton (LEP) radiation experiment (identical to Fox-1A ).
  • Standard Fox-1-Penn State University-Erie MEMS Gyroscope Experiment.
  • the Virginia Tech Camera Experiment (similar to Fox-1D , but with a higher resolution of 640 × 480).

The satellite has a rod antenna for the 70 cm and 2 m band , as well as an antenna for the 23 cm band . Two modes are implemented for downloading the telemetry data:

  • Slow Speed, also known as Data Under Voice (DUV), transmits 200 bps FSK while the FM transmitter is active (beacon or transponder operation).
  • High speed corresponds to 9600 bps FSK and is used as an alternative to transponder operation.

The high speed mode is used for data-intensive experiments, such as B. used for the Virginia Tech Camera experiment.

mission

The satellite was launched on December 3, 2018 at 13:34 UTC with the Falcon 9 flight SSO-A together with 63 other small satellites from the Vandenberg AFB Space Launch Complex 4E in the USA. After the launch, telemetry from the satellite was received by radio amateurs worldwide. Telemetry showed that the systems were working correctly. Commissioning by AMSAT started on December 4th. An abnormality in reception ability was found. After several tests, analyzes and discussions, it appears that Fox-1Cliff cannot become operational as the fourth Fox-1 amateur radio satellite.

Frequencies

  • 145.920 MHz downlink ( FM , data transmission DUV 200 bps and FSK 9600 bps, 400 - 800 mW)
  • 435.300 MHz uplink (FM CTCSS 67.0 Hz)
  • 1,267.300 MHz uplink (FM CTCSS 67.0 Hz)
