Relative Position and Attitude’s Resolution Modeling and Precision Analyzing for Formation Flying Small-Satellites

介绍了编队小卫星无线电相对位置姿态的测量方法,分别采用点估计法和随机滤波法建立了相对位置和相对姿态解算的数学模型,通过仿真给出了两种求取相对位置和相对姿态算法的解算精度。仿真表明,综合使用两种解算方法,可以提高相对位置和相对姿态的测量精度。

The relative position and attitude measurement for formation flying small-satellites was introduced by using wireless ranging. The mathematic model for the relative position and attitude＇s resolution was built through dot evaluation and stochastic filter respectively. The precision of two methods of the resolution was analyzed through simulation. The simulation shows that the measurement precision can be improved by using these two methods synthetically.
