GNSS Multi-system Data Quality Analysis Based on Anubis
The quality analysis of GNSS observation data is an important part of GNSS data preprocessing and precision positioning calculation.In this paper,Anubis software is used to analyze and inspect the observation data of 9 Guangxi continuous satellite positioning reference stations in Hechi City,Guangxi from four aspects,such as data utilization rate,multipath effect,cycle slip ratio and signal to interference plus noise ratio,and comprehensively evaluate the data quality of the stations.The results show that all indicators meet the requirements.At the same time,taking JZ75 as an example,the four systems(GPS,GLONASS,Galileo,BDS)and the data quality of the involved frequency bands are analyzed in detail,which lays a solid foundation for providing reliable navigation positioning and static data solution services for users in Hechi area in the later stage.
