摘要
本文针对工程应用中用户接收到的卫星个数少且卫星几何构型不佳造成的定位精度较差以及可靠性降低的问题,提出了综合多系统组合的定位方法。采用CGO软件处理3种卫星系统组合方案(GPS+BDS、GPS+GLONASS与GPS+GLONASS+BDS)的数据,分别对短基线和中长基线GNSS网进行了数据处理对比研究,基线结果对比表明多系统组合方案中GPS+BDS方案最优,较单GPS或单BDS显著提高定位精度。最后在上述研究的基础上,对多模GNSS网的建立及数据处理提出了一些意见和建议。
Based on the engineering application of the user to receive less number of satellite and satellite geometry due to poor positioning accuracy and reliability, reduce the problems of poor, puts forward the method of the combined system of positioning. With CGO software dealing with three kinds of combination of satellite system scheme （GPS ＋ BDS, GPS ＋ GLONASS and GPS ＋ GLONASS ＋ BDS） data, respectively for short baseline and long baseline GNSS network has carried on the comparative study on the data processing, compared to the baseline results of the combined system plan optimal GPS ＋ BDS, than the single GPS or the BDS can significantly improve the positioning accuracy. Finally, based on the above research, some Suggestions and Suggestions are put forward for the establishment and data processing of multi-mode GNSS network.
