| 摘 要： | 差分GPS可以提高相对定位精度,它在空间交会导航中的应用引起了人们的关注。本文旨在研究在空间交会过程中长距离段差分GPS的精度。文中提出了一种观测模型线性化的新方法,这种方法不需要绝对定位,因此计算量小,而且精度不受两站距离变化的影响。计算机仿真取得了令人满意的结果,表明差分GPS在空间交会的中长距离段导航能满足要求,文中提供的新方法也是可行的。

| Abstract: | Differential GPS can greatly improve the accuracy of relative measurement. Its
application for the navigation of Rendezvous operation between two spacecrafts has drawn
more and more attention. In this paper its accuracy in the case of middle--long range naviga-
tion is studied. A new method for the linearization of observation model is provided, which does
not need absolute positionning and is of little amount of computation; and the accuracy is in-
dependent of the range by using this method. The computer simulation shows that the new
method is available and the achicved results are very satis factory. |
