摘要
为探究和验证在新疆整体地形局限、基准站建设密度不均情况下的新疆北斗卫星地基增强系统(XJ-CORS)的定位精度、解算能力及系统性能,本文首次以新疆全域为测试范围,对实时定位和静态定位精度所涉及的初始化时间和固定率、事后高精度定位性能、时间可用性、空间可用性、兼容性等指标,以及基准站管理、流动站管理、差分数据格式支持、自动运行能力等进行系统全方位测试。测试结果证明,XJ-CORS可为新疆全域用户提供北斗系统米级、亚米级的差分导航定位服务和实时厘米级高精度定位服务。
In order to explore the positioning accuracy,verify solution ability and system performance of XJ-CORS under the condition of the overall terrain limitation and uneven construction density of the reference station in Xinjiang.This paper takes Xinjiang as the test range for the first time.Using the initialization time and fixed rate involved in the real-time positioning and static positioning accuracy,high-precision positioning performance after the event,time availability,space availability,compatibility and other indicators,the system conducts a comprehensive test on the base station management,mobile station management,differential data format support,automatic operation ability.The test results show that XJ-CORS can provide Beidou system meter level and sub meter level differential navigation and positioning service and real-time centimeter level high-precision positioning service for all users in Xinjiang.
