%X On the basis of the theory of on-board GPS precise orbit determination (POD), having analyzed and discussed functional model and stochastic model of on-board GPS low earth orbit (LEO) satellite, the linear combination, zero-differential and differential functional model form and their advantages and disadvantages are put forward. According to different ideas and models for solution,some methods for orbit determinations: one-step POD, two-step POD, dynamic POD, reduced-dynamic POD, geometry POD and kinematic POD are analyzed. Finally, the on-board GPS geometry-dynamic POD method and its prospective are discussed.
