During the last week of May 2003, the solar active region AR 10365 produced a large number of flares, several of which were accompanied by Coronal Mass Ejections (CME). Specifically on 27 and 28 May three halo CMEs were observed which had a signif

The New Hebrides experiment consisted of setting up a pair of DORIS beacons in remote tropical islands in the southwestern Pacific, between 1993 and 1997. Because of orbitography requirements on TOPEX/Poseidon, the beacons were only transmitting to S

Analysing time series of space-geodetic station coordinates, we show that VLBI, SLR and DORIS station motions have a white noise error spectrum, while the majority of GPS station motion have a flicker noise error spectrum. In the latter case, discont

Satellite altimetry is valuable for measuring sea surface topography and global ocean circulation, but only if the satellite's orbit can be computed within a few centimeters. A tracking system called DORIS (Doppler Orbitography and Radiopositioning I

A new space system named DORIS has been developed by the Centre National d'Etudes Spatiales in France with the collaboration of the Institut Geographique National for precise orbit determination and positioning. It is a Doppler-based system with a wo
