摘要
提出采用精确动力学模型应用多颗编队飞行小卫星实现三维定位系统(电子侦察卫星)。为此,首先应用运动学和动力学两种方法建立精确动力学模型和摄动方程,然后进行数学仿真和队形变化的分析,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。
This paper presents 3-Dimension Positioning System (electronic reconnaissance satellite system) using small formation flying satellites. Firstly, accurate dynamics models and perturbation equations are established; secondly, mathematical simulation and analysis of formation evolution are accomplished ; finally, station keeping control strategy is discussed. The simulation results show formation flying satellite system for 3-D positioning possess the advantages of high positioning accuracy and free of the influence of latitude, besides, it can simultaneously realize 3-D positioning globally.
