A Study on the Dynamical Method of GPS Precise Orbit Determination for LEO Satellite

Qi Chen

Abstract

By Combination with simplified dynamical orbit determination algorithm for LEO satellites, and comparison of the accuracy of pure geometric orbit determination with that of dynamical orbit determination in different geometry observed information accuracy, major factors have been quantitatively analyzed to realize precise orbit determination for Ocean Dynamic Environment Satellite by using double-frequency GPS receiver in satellite. The key technical specifications of the GPS receiver in LEO satellite are obtained, and scientific and reasonable references are provided for the whole precise orbit determination system of LEO satellite.
