The SWOT and Sentinel‑6B satellites have recently been integrated into the DORIS processing chain of the CNES/CLS IDS Analysis Center. This contribution presents the current Precise Orbit Determination (POD) performance for these new DORIS missions. POD quality is assessed in particular through the analysis of one‑per‑revolution empirical acceleration amplitudes and orbit residuals. The resulting orbits are also compared with the CNES precise orbits routinely used for altimetry applications. Dedicated single‑satellite solutions for SWOT and Sentinel‑6B are analyzed and evaluated against the latest DPOD2020 reference solution. In addition, the impact of including these two satellites on the CNES/CLS multisatellite solution is investigated.
