| 摘 要： | 伪卫星空中基站的精确定位是构建伪卫星区域定位系统的一个关键问题。分析了伪卫星空中基站的位置误差(相当于卫星的星历误差)对系统定位精度的影响,研究了利用逆用定位原理确定伪卫星空中基站位置的算法和几何精度因子问题,并用Monte-Carlo方法对定位精度进行了仿真,结果表明这种方法是可行的,具有较大的实用价值。

| Abstract: | To position precisely for airborne pseudolites is one of the key technique to constract the pseudolite based regional positioning system.In this paper,the effect of the 'ephemeris error' of the airborne pseudolite on the positioning performance was analyzed,and the feasibility of inverted positioning scheme for the airborne pseudolites and the configuration and geometry of such inverted system are studied.The results of Monte Carlo simulation for positioning accuracy indicate that the scheme is feasible and has great practical value. |
