基于GPS/激光雷达的编队卫星相对导航研究

GPS/Laser Radar Based Relative Navigation for Spacecraft Formation Flying

GPS以及激光雷达都可以作为空间分布式任务相对导航敏感器。文中基于线性Hill方程,结合GPS/激光雷达的测量值设计,相对导航局部UKF滤波器以及组和联邦滤波器(FKF)。仿真结果表明通过组和导航滤波,GPS和激光雷达能够为航天器编队飞行提供高精度的相对位置和相对速度信息。

GPS and Laser radar can be used as a sensor in relative navigation of the space distributed mission. This paper proposes an integrated navigation filter using FKF by measurement of GPS and Laser radar in a formation mission. Simulation results show that GPS/Laser radar integrated navigation can provide precise rela- tive position and velocity information for spacecraft formation flying.
