基于非线性滤波技术的多航天器编队飞行相对导航

Relative Navigation Based on Nonlinear Filtering for Multiple Spacecraft Formation Flying

航天器编队飞行协调工作,必须精确确定各航天器的相对位置和相对速度,即进行编队飞行相对导航,本文提出了一种UKF和卡尔曼滤波组合的非线性滤波算法,并将算法应用于编队飞行的载波相位差分GPS相对导航。

For formation flying of multiple spacecraft, the accurate relative position and velocity must be required. In the paper a combined UKF and Kalman filter algorithm is presented and relative navigation based on CDGPS for formation flying is developed.
