We have implemented the use of DORIS RINEX phase data in the GSFC GEODYN data processing system by constructing range-rate measurements, and have processed such tracking data from the Jason-2, Jason-3, SARAL, and Cryosat-2 satellites. We evaluate DORIS POD for these missions using the new RINEX measurements. We also investigate improved RINEX corrections of the Jason-2 USO frequency made possible through the onboard T2L2 instrument with a preliminary analysis using the products described by Belli et al. (2015).
