DORIS CryoSat

DORIS is a Doppler satellite tracking system developped for precise orbit determination and precise ground location. It is onboard the Cryosat-2, Jason-1, Jason-2 and ENVISAT altimetric satellites and the remote sensing satellites SPOT-4 and SPOT-5. It also flew with SPOT-2, SPOT-3 and TOPEX/POSEIDON.

IDS is an international service which provides a support, through DORIS data and products, to geodetic, geophysical, and other research and operational activities. New proposals for Analysis Centers and temporary or permanent DORIS stations are welcome. See the call for participation.
