摘要： 针对"北斗"双星定位系统不能实现无源定位和精度不能满足用户需求的问题,提出了空基伪卫星增强双星定位系统的方案并研究了其中的关键技术难点——星座布局、空基伪卫星自身定位及系统时间同步问题。研究结果表明,空基伪卫星不仅可以增强双星系统实现三维无源定位,而且具有覆盖范围大、星座布局好等特点,具有广阔的应用前景。

Abstract: Aiming at the problem that Beidou satellite system is unable to realize the passive positioning and the accuracy can not meet the higher requirements of the users,the scheme of airborne pseudolites augmented Beidou satellite system was proposed and the key technologies,including geometry,self-fix of airborne pseudolites and system synchronization,were investigated.Airborne pseudolites can not only augment Beidou system to perform passively,but also have the advantages of larger coverage area,better geometry characteristics and so on.
