Abstract:	The U.S/French Jason-1 oceanographic mission is carrying state-of-the-art radiometric tracking systems (GPS and DORIS) to support precise orbit determination (POD) requirements. The performance of the systems is strongly reflected in the early POD results. Results of both internal and external (e.g., satellite laser ranging) comparisons indicate that the RMS radial accuracy is in the range of 1–2 cm. We discuss the POD strategy underlying these orbits, as well as the challenging issues that bear on the understanding and characterization of an orbit solution at the 1-cm level. We also describe a GPSbased system for producing science-quality orbits in near real time in order to support emerging applications in operational oceanography.
