摘要
给出了评价组合GPS/GLONASS系统可靠性的方法,在此基础上,利用IGS跟踪站的实测数据分别从多余观测分量、定位精度因子和可靠性指标三个方面对GPS/GLONASS精密单点定位系统的可靠性进行了分析,并同GPS单系统进行对比,结果表明,组合GPS/GLONASS精密单点定位系统的可靠性及定位精度均优于GPS系统。
A method of reliability assessment for combined GPS/GLONASS system is provided. On this basis, the reliability of combined GPS/GLONASS PPP system is analyzed using IGS tracking station data from three aspects, namely redundant observation components, positioning accuracy factor and reliability index. Furthermore, the reliability are compared with GPS-only system. The results indicate that the reliability and positioning accuracy of combined GPS/GLONASS PPP system are better than GPS-only PPP system.
