Abstract

This paper studies the observability analysis of multi-station orbit estimation system and provides a modified observable degree algorithm based on condition numbers. First, satellite’s status equation and measurement equation are established and discreted. Then the state transition matrix and the observation matrix are given to calculate the observable matrix. Final, plug station coordinates into the observable matrix and the modified analysis method is been applied to verify that the condition numbers parallel the orbit determination error. The simulation results proved the effectiveness of the modified method.
