FZCORS Data Automatic Processing And Online Calculation Service System

An automatic data processing and online calculation service system named FZCORS is designed and implemented. The problems during its operational, also the expandability of its function and application field are taken into consideration. The automatic system for reference stations data processing is based on Client/Server architecture, integrated GNSS data processing software includes TEQC, Bernese and GAMIT/GLOBK, MySQL database system is also used, to realize FZCORS reference station data automatic processing and management. FZCORS online data calculation service is based on Browser/Server architecture, combined with the TEQC and GAMIT/GLOBK software to realize user data online calculation combined with FZCORS reference stations data. Besides, a involved measurements FZCORS sites selection algorithm is designed and implemented based on Delaunay triangulation properties.The whole month FZCORS observation data at 2014/12 are used for automatic system testing. Both the Bernese and GAMIT/GLOBK output coordinates are within an average bias difference of 2cm according to the statistical output results of FZCORS reference stations processing system.The data used in the online calculation service testing are observation at FUQI and RUAN sites. The precision of online calculation service system increases with the growth of user data length. The differences of each components are less than 2cm using user data more than 6 hours and less than 1cm using user data more can 12 hours compared with the week solutions. System testing and application shows that system can improve the FZCORS reference station data computing efficiency and broadens the range of applications of FZCORS. What's more, the convenience of users is boosted.
