Abstract :
The satellite orbit parameters in the ephemeris and location of land emitter are studied. Universal mathematic models of TDOA and FDOA are deduced using geometric vector. The priori information of TDOA and FDOA between two satellites are analyzed which are selected from Globalstar and Inmarsat satellite communications systems. The simulation results show the effectiveness and universality of the models, and it can be used for estimation and validation of TDOA and FDOA in source localization.
