abstract = "We describe a near-real-time (NRT) precise orbit determination (POD) system for the Ocean Surface Topography Mission/Jason-2 satellite altimeter mission that processes tracking data from the onboard {"}BlackJack{"} Global Positioning System (GPS) receiver. The NRT POD system is now operational, and the resulting orbit solutions are being used to generate a value-added NRT sea surface height product for operational altimetry applications. The NRT GPS-based orbit solution features radial orbit accuracies of 1 cm (RMS) with a latency of < 4 hours. These orbit accuracies are achieved through the use of Ultra-Rapid solutions for the orbits and clocks of the GPS constellation of satellites. We use satellite laser ranging tracking data and sea surface height crossover residuals as external metrics for evaluating orbit accuracy. We also provide comparisons to other orbit solutions of varying latencies to illustrate the trade between accuracy and timeliness.",
