| 摘 要： | 目前对相位观测值周跳的探测和修复已有多种方法，但是各种方法都不是很完善。通过用相位观测值相邻历元求差法和多项式拟合法对周跳进行探测和修复，算例结果表明相位观测值相邻历元求差法不仅能准确地锁定发生小周跳的历元，而且能高效地修复观测值。该方法执行效率高，实用性强，尤其适合动态定位的应用。

| Abstract: | There are many methods of cycle-slip detection and correction,but every one has disadvantage.The paper uses two different ways phase difference between sequential epoch and polynomial fitting to detect and repair cycle-slip,and the result illuminates that the method of phase difference between sequential epoch not only can exactly lock the epoch having cycle-slip,but also can repair the carrier phase value efficiently.This method has high practicality and efficiency,especially for kinematic GPS positioning. |
