摘　　要：为了全面、有效地评估湖南省连续运行基准站系统兼容BDS升级后的性能,提出软硬件相结合、内外业相结合的方法,利用对比分析和时空分析等手段,从兼容性、稳定性、用户固定比例、定位精度、时空可用性等方面进行测试分析。结果表明:升级后的系统兼容各类主流设备,监控功能更加完善,观测数据更加丰富,用户体验有所提升;RTK平面和高程定位精度能够满足设计要求;初始化时间有显著提升,在覆盖湖南省的基础上能一定程度地覆盖临近省份;此外,BDS的引入能解决某些特殊环境下的定位问题。In order to evaluate the performance of upgraded BDS-compatible HNCORS network,the paper proposed a schedule which combines software with hardware,indoor with field work,uses the approaches of comparative analysis and spatial-temporal analysis,and tests from the aspects of site compatibility,system reliability,monitoring function,satellite observations,fixed user ratio,positioning precision,rover compatibility,initialization time,time-spatial availability and so on.Result showed that the upgraded system could update user experience by compatible to the most popular terminal equipments,comprehensive monitoring functions and rich satellite observations;the positioning precision of RTK on horizontal and vertical directions could meet the design requirements well;the initialization time could be improved largely,thus it could not only cover Hunan province but also the nearby districts to some extent;moreover,the introduction of BDS could help the positioning performance under some special environments.
