摘要
提出应用多颗编队飞行小卫星实现的三维定位系统。首先建立精确动力学模型和摄动方程,然后进行数学仿真和估算三维位置精度,最后讨论位置保持控制策略。仿真结果表明:编队飞行三维定位系统定位精度高,不受纬度影响,而且可以实现全球同时定位功能。
A 3-Dimension Positioning System using small formation flying satellites is presents in this paper. Firstly, accurate dynamics models and perturbation equations are established, mathematical simulation and estimation of 3-D positioning accuracy are accomplished secondly, the station keeping control strategy is discussed lastly. The simulation results show the formation flying satellite system for 3 -D positioning has the advantage of high positioning accuracy, and is free of the influence of latitude. Besides, it can simultaneously realize the 3-D positioning globally.
