Study of Global Station-Selection and Application in Precise Orbit Determination Based on TIN Net
Abstract In this paper, a new station selection method is proposed based on the triangulated irregular network(TIN) topology. This method is used to study the precise orbit determination accuracy, efficiency and station saturation point. The experimental data shows that: when under conditions of the global distribution network, 70 stations can succeed in precise orbit determination with precision better than 3 cm, while computational efficiency is increased by 2 times compared to 140 stations. When the number of stations reaches 90, the precision lifting slows. Ensuring orbit determination precision to establish suitable monitoring stations has importance on the global monitoring network construction of the Beidou navigation system.
