This study outlines the current status of DORIS data processing using the GipsyX software at the IGN-IPGP/JPL analysis center within the International DORIS Service (IDS). We detail the methodological evolution implemented since late 2023 for the ITRF2020-u2024, coinciding with the operational reactivation of the analysis center (AC).

Our analysis focuses on a comparative assessment of precise orbit determination (POD) results against SSALTO orbits, positioning estimates relative to the DPOD2020 reference frame, and Earth Orientation Parameters (EOPs) against the EOPC04 series. This enables a thorough evaluation of the consistency and accuracy of our products relative to established benchmarks.

In addition to describing these advancements, we highlight ongoing and planned developments aimed at enhancing processing capabilities. Among these, we present preliminary results from simultaneous multi-satellite data analysis, which incorporates separate modeling of ground and satellite clocks. These developments are expected to improve the temporal and spatial resolution of DORIS-derived geodetic products, ultimately contributing to the broader geophysical and climate-monitoring goals of the IDS.
