摘　　要：针对由于单点定位精度较低,难以引导飞行器进场着陆的问题,提出一种飞行器着陆的引导方法:利用北斗卫星导航系统(BDS)伪距差分定位数据来引导飞行器着陆;并建立BDS伪距差分定位模拟环境。实验结果表明,在短基线情况下,BDS伪距实时差分定位的位置精度小于1 m,证明了BDS伪距差分定位技术用于引导飞行器进场着陆的有效性。Aiming at the problem that due to the low accuracy of single point positioning,it is difficult to guide aircrafts in approach and landing,the paper proposed a guiding method for aircraft landing:pseudo range differential positioning data of Beidou navigation satellite system(BDS)were used to guide the landing;and the simulation environment of Beidou pseudo range differential positioning was established.Experimental result showed that the position accuracy of real-time Beidou pseudo range differential positioning would be less than 1 m in the case of short baselines,which could prove the feasibility of the proposed method.
