一种GPS周跳探测与修复的组合算法
A Combined Algorithm for Cycle Slips Detection and Correction
摘要
Abstract
Cycle slip is an important affecting factor of the GPS positioning accuracy. Cycle slip detection and correction is always an important issue. Firstly, the classic cycle slip detection algorithms of the ionized layer remnant method of difference and the width lane phase narrow reduce false method were researched. Based on advantages and disadvantages of the two methods, the cycle slip detection and correction of the combination algorithm was designed. According to cycle slips' integer characteristics and making use of searching for integer solution, the cycle slips were determined and corrected. Test results showed that the new method was effective and practical.关键词
