The method of the RINEX DORIS data processing

The INASAN's space geodesy group is one of the analysis centre of the French satellite Doppler radio system DORIS (Determination of Orbit and Integrated Radiopositioning by Satellite) and beginning from 1998 on the regular basis delivers own products to the International DORIS Service (IDS). Currently INASAN processes DORIS data in the doris2.2 format using GIPSY-OASIS II software package developed by JPL (USA). Starting from the JASON-2 satellite launch in 2008 the DORIS measurements began to use the new RINEX format which will be the only format for the DORIS data in the near future. Taking into account the fact that the current GIPSY-OASIS II version can't process RINEX DORIS data, the INASAN's space geodesy group has begun to develop own software package for RINEX DORIS data processing. The first results of that processing were obtained in the late 2018. This article describes the method of the RINEX DORIS data processing.
