The 2.7 version of VTS includes improvements from the “DORIS” project contribution. That’s why the full name of this version is VTS 2.7 “DORIS”.

The DORIS project

DORIS (Doppler Orbitography and Radiopositioning Integrated by Satellite) is a Doppler satellite tracking system developped for precise orbit determination and precise ground location. It is onboard the Cryosat-2, Jason-2, HY-2A, SARAL, Jason-3 and Sentinel-3A altimetric satellites. It also flew with SPOT-2, SPOT-3, SPOT-4, SPOT-5, TOPEX/POSEIDON, ENVISAT and Jason-1.
