GPS/GLONASS周跳探测与修复方法
GPS/GLONASS Cycle Slip Detection and Repair Method
摘要
Abstract
In order to accurately detect and determine the GPS/GLONASS cycle slip,especially small cycle slip,a new GPS/GLONASS cycle slip detection and identification program was proposed based on ionosphere residual method combined with phase minus pseudo range method.Firstly,the GPS/GLONASS cycle slip was detected by ionosphere residual method.Secondly,the search scope of cycle slip was fixed by phase minus pseudo range.Then,all candidate values were searched according the scope of cycle slip.At last,the optimal value of cycle slip was determined by the ionosphere residual value closet to observation noise.The GPS/GLONASS observations of parts of Jiangsu CORS and Qingdao CORS were processed by the method.It was showed that the method had the ability of detecting and fixing small cycle slip,and that the search success ratio,detecting resolution and repairing accuracy were 95％,0.03 cycle and ±0.031 cycle respectively.关键词
