| Abstract: | This paper introduces ephemeris parameters of the GPS satellites, and analyzes their shortcomings for the GEO, IGSO and MEO satellites. An improved ephemeris parameters and their estimation arithmetic are developed and applied in the GEO, IGSO and MEO satellites. Test results show that the improved ephemeris parameters and their estimation arithmetic can be applied to the GEO, IGSO and MEO satellites, and the loss of the fitting precision of the ephemeris parameters can satisfy the need of the satellite rapid capture. |
