摘要: 广东省连续运行卫星定位服务系统(GDCORS)建成了兼容多星系统的北斗地基增强平台,组织开展了新平台与原平台的外业测试. 并从内符合精度评定、重复性精度评定、外符合精度、初始化时长等方面对网络实时动态（RTK）定位结果进行了统计和比对分析. 测试结果表明,新平台能够提供高可靠性、高精度的网络RTK服务. 文中研究结果可为GDCORS用户使用新／原平台提供实际应用参考.Abstract: Ground based augmentation platform on compass was built from Guangdong Continuous Operational Reference System (GDCORS), and the positioning performance between the new and old platform had been tested. The results of RTK positioning are compared and analyzed from the aspects of internal accuracy， repeatability accuracy, external accuracy evaluation and initialization time. The Result indicate that the new platform can provide Network RTK service with high reliability and high accuracy,which can provide practical reference for GDCORS users to use the new／original platform.
