Milestone -- Commissioning of the SwissCube-1 control room

Successful handshake between the spacecraft and the Noordwijk (NL) control room. This control room is connected to the central servers in Lausanne (CH) via an internet link. The spacecraft telemetry is received through a local VHF-UHF-SBand antenna.
