Research on standardized operation and maintenance technology of CORS in provincial region
This paper discusses from coordinate frame maintenance,reference station maintenance and observational data maintenance based on the practical operation maintenance experience and fault statis-tics analysis of Beidou ground-based augmentation system in Hubei Province.Firstly,the coordinates are updated once a year on the whole network to maintain the stability of the coordinate frame.Secondly,for the maintenance of the reference station,the annual inspection frequency of each reference station is set to 2~3 times,and the common faults such as power failure and network failure are prevented and dealt with.Finally,in terms of data maintenance,data quality analysis is carried out every year to ensure that technical indicators such as data utilization and multipath effect meet the requirements.The results show that the implementation of the maintenance strategy can ensure that the utilization rate of Hubei Beidou ground-based augmentation system throughout the year can remain above 95%,and the annual normal operation rate is as high as 98%.These experiences and methods can provide a strong guarantee for the stable operation of Beidou ground-based augmentation system in Hubei Province,and can also provide reference for the operation maintenance of other regional reference stations.
