摘　　要：在目前常用的周跳探测与修复方法基础上,分析利用GPS组合观测值来探测修复周跳的3种方法,通过模拟的实验结果证明其有效性,比较各个方案的特性,并引入LC-PC衡量标准比较各方案探测修复周跳的能力。Based on the surrent methods for cycle slip detection and correction, three cycle slip detection methods using GPS combined observations are analyzed. First, the validities of these methods are proved through some experiments. Second, the features and limitaions of these methods are disscussed. Then, an evaluation standard called LC-PC is introduced to compare the cycle detection capabilitiy for each method.
