The mathematical model of the combined orbit determination is given in this article, and the results of six experiments are used to demonstrate the contributions made by the borne observation value of LEO satellite to the GPS precision orbit determination. The results of these experiments indicate that the accuracy of the GPS satellite orbit can be improved by 40% on average by adding the observation data of three LEO satellites, when compared with the orbit determination results by only using forty-three ground tracking stations.
