对昆明市GPS参考站升级为GPS/GLONASS双星系统后RTK测量的分析研究

The Analysis of RTK Measurement System after GPS Reference Station of Kunming Being Upgraded to GPS/GLONASS

以昆明市GPS参考站KM-CORS系统为研究对象,在KMCORS系统升级为GPS/GLONASS系统后进行了实验数据采集。着重介绍了GPS/GLONASS双星系统组合测量的主要误差源及其性质;对GPS与GPS/GLONASS的定位精度、可靠性进行了多方面的比较分析;讨论了GPS/GLONASS双星系统参考站的优势及应用前景。

This paper studied the Kunming GPS Reference Station system. After upgrading the KMCORS system to a GPS/GLONASS system,we collected the experimental data;the error sources and its properties are introduced and analyzed;Comparison and analysis on combined surveying of GPS/GLONASS;the application and advantages of combined GPS/GLONASS positioning system were discussed.
