Title: The broadcast ephemeris parameters design of high orbit navigation satellite
Abstract: The physical definition of navigation satellite broadcast ephemeris parameters are analyzed by the non-spherical gravitational potential and the third body perturbation theory, and their theoretic bounds are concluded. The resonance affection on high orbit navigation satellite is synthetically analyzed, which disturbed the applicability of the Kepler ephemeris fitting arithmetic on GEO, and the i≈0 and J2,2 factors mainly cause the inapplicability. To solve the former problems, an arithmetic named constraints adjustment with parameters dynamic weighting is advanced, which is proved to be effective to stabilize the ephemeris parameters fitting results or to limit all parameters such as Δn within the bounds of the interface.
