Abstract:	The paper discusses the design of the GPS real-time navigation system for the Sentinel-3 mission and presents its validation using signal-simulator test data as well as GPS flight data from the GRAS receiver on MetOp. Trade-offs between accuracy, robustness and run-time performance are discussed taking into account the specifics of the Sentinel-3 mission. It is demonstrated that a 1m 3D rms position accuracy and a better than 0.5 m radial accuracy can be achieved during routine operations. Further attention is given to the robust handling of orbit correction maneuvers with minimum operational implications.
