Deep Space 1 (DS1) is a NASA satellite developed to test some cutting-edge technologies and concepts. It was launched in October 1998, with a solar electric ion propulsion system. Under the lead of TU Braunschweig, a magnetic field experiment was developed to measure both the interplanetary magnetic field and the magnetic field caused by the ions emitting from the propulsion system. Valuable data were obtained during the flybys of Asteroid Braille and Comet Borrelly.

IWF is mainly responsible for the ADC part of the DS1 Fluxgate Magnetometer (FGM). The DS1 FGM is a prototype of the Rosetta Orbiter Magnetometers (RPC-MAG). The measured data were used to study the solar wind interaction with the asteroid and the comet.

More information on the DS1 Magnetometer can be found at TU BS.

More information on the Mission is given at DLR.
