摘要
介绍产生周跳和常用的探测与修复周跳方法,并通过用双频相位求差法和多普勒方法对周跳进行探测和修复,算例结果表明两种方法均能准确地锁定发生小周跳的历元,且能高效地修复观测值。两种方法执行效率高,实用性强,适合RTK等动态导航定位的应用。
Firstly,the production of cycle slips and common methods for detecting and repairing cycle slips are briefly shown;then the paper uses two different ways phase difference between sequential epoch and Doppler to detect and correct cycle slips,and the result illuminates that two ways both not only can exactly lock the epoch having cycle slips,but also can repair the carrier phase value efficiently.Two methods have high practicality and efficiency,especially for kinematic GPS positioning such as RTK.
