Abstract:	A single frequency GPS receiver was launched with the Extreme Ultraviolet Explorer (EUVE) mission in the summer of 1992. The low altitude of the EUVE, the placement of dual antennas directly on the spacecraft body, and the Ll only capability of the receiver on-board allows a unique opportunity to investigate error sources and the level of accuracy obtainable under such conditions for a variety of future satellite missions. GPS data sets from several different periods have been processed at the Jet Propulsion Laboratory with the GIPSY-OASIS II data analysis software. Data from EUVE and from a global network of Rogue GPS receivers were differenced to eliminate the effects of selective availability. Methods for removing the ionosphere delay error from the single frequency data, and orbit solutions utilizing the reduced dynamic technique were investigated. Orbits were compared to those generated with the on-board algorithm, and to solutions from the Goddard Trajectory Determination System. The resulting orbits were good to a few meters. Studies have begun to determine the accuracy attainable with real-time Kalman filtering for the EUVE data. Solutions simulating real-time processing are then compared to the best reduced dynamic differential solutions.
