QB50P2 (after the start also European-OSCAR 80, EO-80 ) is a Belgian 2U Cubesat and amateur radio satellite , which was developed under the direction of the " Von Karman Institute for Fluid Mechanics " with the cooperation of the Dutch company ISIS BV. 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).

In addition, the satellite carries a repeater that was built by AMSAT -France. The repeater is in exchange 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

  • 145.880 MHz 1200 Bd BPSK or CW telemetry (beacon)
  • 435/145 MHz FM converter (uplink frequency not yet published)
  • 145.840 MHz downlink (also for 9600 Bd FSK data transmission)
