QB50P1 (after the start also European-OSCAR 79, EO-79 ) is a Belgian 2U- Cubesat and amateur radio satellite , which was developed under the direction of the " Von Karman Institute for Fluid Mechanics " in cooperation with the Dutch company ISIS BV. The QB50P1 carries a linear transponder known as FUNcube-3 as an additional payload. QB50P1 and QB50P2 are pre-missions of the QB50 satellite program . This satellite program was funded by the European Commission's FP7 research framework program .

mission

The satellite was launched on June 19, 2014 in a cluster launch of a total of 37 satellites from the Jasny cosmodrome with a Dnepr launcher.

The primary function of the satellite is to test the systems for the CubeSats of the QB50 mission. This affects the assemblies:

  • Attitude determination and attitude regulation
  • mass spectrometry
  • Oxygen flow probe,
  • Control software
  • Deployment mechanism (Quadpack Deployer).

The FUNcube-3 linear transponder was built by AMSAT -NL and the Dutch company ISIS BV. The transponder is in return for the support and use of the amateur bands by the primary QB50 mission. The transponder is said to be activated after the primary mission is completed. This was estimated at six months after commissioning.

Frequencies

  • 145.815 MHz 1200 Bd BPSK or CW telemetry (beacon)
  • 435/145 MHz inverting linear transponder for SSB / CW with 400 mW transmission power
  • 435.035 - 435.065 MHz uplink
  • 145.935 - 145.965 MHz downlink
