Challenging Minisatellite Payload (CHAMP) was a German satellite launched July 15, 2000 from Plesetsk, Russia and was used for atmospheric and ionospheric research, as well as other geoscientific applications, such as GPS radio occultation, gravity field determination, and studying the Earth's magnetic field.[3][4]
CHAMP was managed by GeoForschungsZentrum (GFZ) Potsdam.[5]
The spacecraft is the first application of Astrium's "Flexbus" platform; GRACE was the second.[6] A heavily modified version flew as the GOCE mission.[7]
