摘要
提出了使用伪卫星来增强北斗系统的方案,并研究了此系统的定位原理和几何布局。仿真结果表明,此方案是可行的,能够独立实现实时、高精度的无源定位,为发展区域定位系统提供了一种成本相对较低的新思路。
“Bei dou” double-star positioning system is a kind of regional positioning system. But because of the limitation of the number of satellites, double star system cannot realize the real time 3-D passive positioning, tn this paper, a new idea of using pseudolites to augment the double star system is put forward, and the algorithm and geometry of this augmented positioning sysem is studied. The simulation results indicate that the idea of double star system augmentation with pseudolites is feasible and can fulfill the real-time passive positioning with the high precision independently, which offer a new way to develop the independent regional satellite positioning system at a relatively lower cost.
