Application of GPS triple-frequency data in detection and repair of cycle slip and gross error

LIU Xu-chun~(1,2),WU Yue~3,ZHANG Zheng-lu~1,MENG Yang~1 (1.School of Geodesy and Geomatics,Wuhan University,Wuhan 430079,China;2.Surveying and Mapping Engineering Department,Beijing Institute of Civil Engineering and Architecture,Beijing 100044,China;3.Working Headquarters for Prevention and Treatment of Geologic Hazards in TGR Area,Yichang 443000,China)  
Used stimulant multi-frequency carrier data to detect and repair cycle slips and gross error in different conditions,utilizing the traits of some long wave combinations with the principle of traditional pseudo-range/carrier phase combination.Through the example which made a preprocessing of original carrier phase observation in a GPS baseline,the result indicates that we can repair multifarious real-time cycle slips completely and detect real-time gross error up to 0.2 cycle.
