Review of GNSS Cycle Slip Detection
摘要
Abstract
Cycle slip is the integer cycle slip caused by signal interruption in Global Navigation Satellite System(GNSS)carrier phase observation,which seriously affects the correct fixing of integer ambiguity and positioning accuracy.The technical characteristics and applicability of various cycle slip detection methods are systematically analyzed to provide theoretical support for high-precision GNSS positioning.In order to address the cycle slip problem in GNSS carrier phase data,this study first theoretically deduces various traditional cycle slip detection methods and analyzes their advantages and disadvantages,and systematically classifies and summarizes the common single-frequency and dual-frequency cycle slip detection methods.Through the simulation and experimental verification of different methods,the results show that:single-frequency cycle slip detection methods are easy to operate,but the sensitivity to small cycle slips detection is low and vulnerable to interference;dual-frequency detection method can effectively eliminate most of the influence of the error source,and the detection accuracy is improved to the 1-cycle level,but they have the defect of being unable to detect specific insensitive cycle slip pairs.For the above problems,the success rate of cycle slip detection is usually improved by combing complementary detection methods.In different scenarios,the selection of appropriate repair methods for cycle slip detection is crucial to the detection results of cycle slip.关键词
