摘　　要：为了研究基于BDS系统的多模CORS(Continuously Operating Reference System)网络RTK定位性能,本文在全球定位系统(GPS,Global Positioning System)的基础上融合BDS系统与GLONASS(Global Navigation Satellite System)系统,分别构建GPS/BDS双星CORS系统与GPS/BDS/GLONASS三星CORS系统,通过对比与分析双星系统与三星系统观测数据的解算精度,得出的结论为:双星CORS系统的内符合精度、外符合精度与时间序列精度较三星系统均更高,同时,双星系统、三星系统的平面精度要大于高程精度。将双星CORS系统应用于城市地形测绘中的控制测量中,结果表明,双星CORS系统能够在保证数据精度的前提下,提高外业作业效率。In order to study the RTK positioning performance of multi-mode CORS(Continuously Operating Reference System)network based on BDS system,this paper integrates BDS system and GLONASS(Global Navigation Satellite System)system on the basis of GPS(Global Positioning System),and constructs GPS/BDS double star CORS system and GPS/BDS/GLONASS three Star CORS system respectively.By comparing and analyzing the calculation accuracy of the observation data of the double star system and the three star system,it is concluded that the internal coincidence accuracy,external coincidence accuracy and time series accuracy of the double star CORS system are higher than those of the three star system.At the same time,the plane accuracy of the double star system and the three star system is greater than the elevation accuracy.The application of the double star CORS system in urban terrain control survey shows that the double star CORS system can improve field work efficiency while ensuring data accuracy.
