  1. DORIS, 30 years of continuous operations at the heart of the of altimetry mission performance for oceanography and geodetic applications

    Publishing date:

    February 27, 2020

    The DORIS system (Doppler Orbitography and Radio positioning Integrated by Satellite) was designed and developed in the early 1980s by CNES, IGN and GRGS to determine satellite positions with high accuracy to support altimetry missions dedicated to ocean monitoring.

  2. DORIS the space surveyor serving the ITRF

    Publishing date:

    January 13, 2016

    The DORIS system (Doppler Orbitography and Radiopositioning Integrated by Satellite), conceived and developed by CNES, France’s national mapping, survey and forestry agency IGN and the French space geodesy research centre GRGS, has just turned 25. From the early 1990s, DORIS has driven effective exploitation of satellite altimetry data by supplying orbital parameters with centimetre accuracy. As a key element of geodetic and geophysical research, DORIS provides data for the International Terrestrial Reference Frame (ITRF), of which a new version—ITRF2014—is about to be released. And with new instruments soon set to launch on the Jason-3 and Sentinel-3 satellites, the DORIS constellation still has many more years of service in store.
