| 摘 要： | 针对大型无人机与民用客机在同一空域环境中运行,使用传统的单点定位方法,定位精度低,可靠性差,不能满足大型无人机进近着陆需求的问题,提出了一种提高大型无人机进近着陆过程中的定位精度的方法。利用陆基增强系统,为传统的伪距观测提供差分修正,使大型无人机在进近着陆过程中获得更精确的高程信息。实验结果表明,相比于传统的单点定位方法,利用陆基增强系统进行无人机进近下降着陆,在很大程度上提高了无人机的高程定位精度,确保了无人机在进近着陆过程中的运行安全。研究结果为无人机与民用客机的联合运行以及未来"空管一体化"标准的制定提供了重要理论支撑。

| Abstract: | The unmanned aerial vehicles(UAVs)and civil airplanes are tend to be inter-operation in the same airspace.The traditional single point positioning technology,which exhibits the low accuracy and reliability,is not able to meet the requirement for the approaching landing requirement for the large UAVs.In this paper,a GBAS based positioning method is proposed to provide the differential corrections to the traditional pseudorange measurements for improving the height accuracy.It is demonstrated from the field test that,GBAS based landing system can significantly improve the UAV height positioning accuracy,compared to the traditional single point positioning.Therefore,it will ensure the safe operation for the UAV descending and also provide the important principle support for the future all-in-one operation standard setting in the Air Traffic Management(ATM). |
