摘要
BDS现可为亚太地区提供无源定位、导航、授时服务。通过研究BDS伪距单点定位算法,并考虑了BDS混合星座下的不同卫星位置计算方法,编程实现了BDS伪距单点定位。研究成果显示,BDS伪距单点定位三维坐标精度优于20 m,x, y, z方向上的精度优于10 m。研究验证了BDS伪距单点定位的可用性,通过算法得到的伪距单点定位结果完全满足普通用户导航定位所需的精度要求。
BDS can provide passive positioning,navigation,and timing services for the Asia Pacific region.BDS pseud orange single point positioning algorithm has been studied in this paper,and the different calculation methods under the mixed constellation have also been taken into account.Then,programming of BDS system pseudo range single point positioning,and making the positioning accuracy analysis.Results show that the BDS system precision of pseud orange single point positioning three-dimensional coordinate is better than 20 meters,and the..accuracy ofx direction,y direction and z direction are better than 10 meters.This study tested the pseud orange single point positioning availability of the BDS system,and the results through this algorithm fully meet the ordinary users'accuracy requirements for navigation.
