2017surname Nian7moon12On March 28, 2012, a technical team from Nanjing Cobo and their delegation4People led by Project Manager Gao Shen went to Xin'anjiang Hydropower Plant of Hangzhou State Grid Xinyuan Hydropower Co. to carry out the environmental test of the Dam Beidou Automated Displacement Monitoring Project.
Data quality isGNSSThe accuracy and reliability of positioning is guaranteed, and it is affected by many factors such as the health condition of the satellite, the receiver, the antenna, the observation environment and so on. The key to determining whether the receiver hardware and observation environment meet the actual requirements is how to evaluate the quality based on the measured data. The key to determine whether the receiver hardware and observation environment meet the actual requirements is how to evaluate the quality based on the actual observation data. Eliminating the poor quality data from the actual observation data isGNSSThe key to data preprocessing.
For this reason, this test mainly collects data from each dam section in turn, and based on the professional quality check software of Kobelco, the quality analysis and statistics of these single station data under different observation environments are carried out, so as to provide reference for the actual monitoring work.
within a period of10During the days of testing, the Kibo team gave full play to the spirit of bravery and hard work, and completed all the contents of site selection, line deployment and control, software installation and data collection in the testing phase, and the whole testing phase was successfully completed according to the original plan.
