A New Method of Real-time Cycle-slip Detection and Reparation in BDS Triple-frequency Un-differenced Observations
摘要
Abstract
Based on the principle of triple-frequency carrier phase combination,this paper puts forward a new method in cycle-slip detection and reparation,which uses pseudo-range and phase combination,whose coefficient is(0,-1,1),then uses a geometry-free phase combination (1,4,-5) and a geometric phase combination (4,-2,-3).Through the differential combination observations between epochs,the estimated value of cycle-slip is calculated.The method is proved by experiments and there is no insensitive cycle-slip,and it can effectively detect and repair the cycle-slip in real-time.关键词
