The Orbiter magnetometer: RPC-MAG

The Orbiter-Magnetometer is part of the Rosetta Plasma Consortium (RPC) and was developped in a close cooperation with the Imperial College (London). The instrument consists of two identical fluxgate sensors mounted on a 1.5 m long boom outside the spacecraft andan electronics box placed inside the orbiter.The sensor has beeen designed and manufactured in lead-management by Prof. Dr. Karl-Heinz Glaßmeier at the IGEP in Braunschweig. The development of the electronics was a teamwork with the IWF in Graz.
