摘要
为了验证利用全球导航定位系统(GNSS)观测数据进行CORS稳定性监测的可行性,利用区域CORS站2018—2019年的GPS、BDS、GLONASS、Galileo观测数据,以GPS数据处理结果为参照,对BDS、GLONASS、Galileo基线解算的各项精度指标和坐标时间序列进行了分析比较。结果表明,GPS数据处理结果的精度优于BDS、GLONASS、Galileo;GLONASS和Galileo的坐标时间序列与GPS有较好的一致性,均优于BDS,但4个卫星系统均可满足区域CORS稳定性分析的需求。
To verify the feasibility of using Global Navigation Satellite System(GNSS)observation data for Continuous Operating Reference Station(CORS)stability monitoring,this article used GPS/BDS/GLONASS/Galileo observation data of the regional CORS station from 2018 to2019 for a total of two years.Taking the GPS data processing results as a reference,we analyzed and compared various accuracy indicators and coordinate time series calculated by the BDS/GLONASS/Galileo baseline.The results show that the accuracy of GPS data processing results is better than that of BDS/GLONASS/Galileo.The coordinate time series of GLONASS/Galileo is in good agreement with GPS,and both are better than BDS,but the four satellite systems can meet the needs of regional CORS stability analysis.
