| 摘 要： | 在星间无线电相对状态测量系统中,针对三星编队星座相对状态联合解算时观测方程的几何结构比较弱、法方程病态的情况,提出了基于部分参数加权平差的相对状态解算方法。首先给出三星编队星座系统相对状态解算的数学模型,然后比较了联合解算方法和部分参数加权平差方法,最后对仿真结果进行分析。分析结果表明,使用基于部分参数加权平差的相对状态解算方法能够自主确定三星编队星座的相对状态。

| Abstract: | In the system of relative position and attitude determination based on wireless technology , the relative states autonomous determination of three satellites formation is studied.Using parameter adjustment, matrix is singular to working precision because observation geometry is very weak. In order to resolve this problem, a new method based on weighted partial parameters adjustment to get relative position and attitude information is gived. Firstly, the system model is built. Then weighted partial parameters adjustment compares with parameter adjustment. Lastly. the result of simulation is analyzed. The results show that the relative states of three satellites formation are autonomously determinate through using the metthod based on weighted partial parameters adjustment. |
