Wouter Weggelaar PA3WEG reports on the two QB50 precursor satellites QB50p1 and QB50p2, launched on June 19, 2014 carrying amateur radio transponders.

The QB50 precursor satellites are in good health and still being commissioned. These satellites are part of a risk-reduction program for the QB50 main mission.

These satellites are also carrying amateur radio transponders:
– QB50p1 carries the FUNcube-3 transponder system by AMSAT-UK and AMSAT-NL
– QB50p2 carries an FM transponder by AMSAT-Francophone

I am grateful to be able to announce that these two CubeSat Satellites have been awarded OSCAR numbers by AMSAT-NA: QB50p1 shall be known as European OSCAR 79 or EO-79, and QB50p2 shall be known as European OSCAR 80 or EO-80. Thank you AMSAT-NA!

The transponders are expected to be switched on after the main mission, which lasts about 6 months depending on progress made.
