摘要
BDS-3已正式开通全球定位服务,会逐步取代GPS在我国各领域中的应用,因此评估BDS-3的定位性能具有一定的科学指导意义。本文基于多个MGEX跟踪站BDS-3实测数据,评估了BDS-3新频率单点定位性能。研究结果表明,BDS-3卫星可用情况良好,B1C和B2a伪距单点定位精度较优,整体水平精度优于1 m,高程精度优于2 m。B1C/B2a双频精密单点定位精度可以达到厘米级,最高精度达到1 cm左右。
BDS-3 has officially opened the global positioning service,which will gradually replace the application of GPS in various fields in China.Therefore,the evaluating the positioning performance of BDS-3 has certain scientific guiding significance.Therefore,this paper evaluates the BDS-3's new frequency single-point positioning performance based on the measured data of multiple MGEX tracking stations BDS-3.The research results show that the BDS-3 satellite is available in good condition,the B1C and B2a pseudo-range single-point positioning accuracy is better,the overall horizontal accuracy is better than 1m and the elevation accuracy is better than 2 m.The B1C/B2a dual frequency precision single point positioning accuracy can reach cm level,and the highest accuracy can reach about 1 cm.
