摘　　要：介绍了当前单频精密单点定位周跳探测的主要方法。采用IGS跟踪站1s采样率的观测文件,并使用TEQC软件分别生成15s和30s采样率的另外两组观测数据,在事先利用Bernese软件确定三组数据无周跳的前提下,人为加入不同周数的周跳,通过自编软件,采用不同周跳探测方法对其进行周跳探测,并对结果进行比较与分析,探讨了各方法探测周跳的能力及适用范围,为单频非差相位观测值中选择合适的周跳探测方法提供了一定的依据。The methods of cycle-slip determination in single-frequency precise point positioning is discussed in this paper. An observation file down loaded from IGS（International GNSS Service） analysis center is genernated into three kinds of different sampling intervals using TEQC software. On the premise of non cycle-slip ex- ist in the three genernated data, of which the sampling intervals are 1-second, 15-second, 30-second, respectively, some different cycles-slips are intentionally added into the data. Then several methods are used to detect the artificial cycle-slips with the help of a computer program designed by the author. Through the comparison of the tests,the detectability and suitability varies from methods and sampling intervals,which provides a basis for the eyele-slip determination in single frequency precise point positioning.
