摘要
为分析BDS-3不同星座对Galileo定位系统的影响,本文基于中国及周边区域多个IGS跟踪站,对比分析了BDS-3不同星座与Galileo组合SPP、PPP、RTK性能。实验结果表明,IGSO卫星和GEO卫星都能提升Galileo定位性能,但MEO卫星优于数量优于IGSO卫星,因此提升效果优于IGSO卫星;MEO卫星使Galileo系统SPP定位精度提升量在分米级,使PPP和RTK定位精度提升量在厘米级;GEO卫星加入解算没有影响,原因有待进一步分析。
In order to analyze the influence of different BDS-3 constellations on Galileo positioning system,this paper compares and analyzes the SPP,PPP,RTK performance of different BDS-3 constellations and Galileo based on multiple IGS tracking stations in China and surrounding areas.The experimental results show that both IGSO satellites and GEO satellites can improve the positioning performance of Galileo,but MEO satellites are better than IGSO satellites in quantity,so the improvement effect is better than IGSO satellites.MEO satellites improve Galileo system SPP positioning accuracy at the decimeter level.The improvement of PPP and RTK positioning accuracy is at the centimeter level,and the addition of GEO satellites to the solution has no effect.The reason needs to be further analyzed.
