Abstract:
In practical application, it is important to determine the target satellite orbit by using space-based angle observation data. Firstly, in order to solve this problem, an optimal mathematical model STSM is introduced in this paper. Secondly, using the polynomial fit method to a series of space-based angle observation data, the approximate initial value for the STSM can be obtained. Thirdly, based on a detailed analysis of the characteristics of the STSM objective function, the basic principle used to find the optimal solution of STSM is introduced. Finally, the simulation results are given out, which shows that the method given in this paper is both feasible and robust.[著者文摘]
