周跳是影响基线解算精度的一个重要因素。从周跳探测方法的基本原理出发，利用实测数据详细研究分析高次差法、相位减伪距法和电离层参差法3种周跳探测方法的特点。分析结果表明，电离层残差法适合小周跳的探测，相位减伪距法和高次差法适合大周跳探测，且前者探测效果更佳；为更好地完成周跳探测需将多种方法组合使用。研究结果有助于提高 GPS基线解算精度，便于进行相应软件开发。

Cycle slip is an important factor affecting the accuracy of baseline solution.From the basic principle of cycle slip detection method,the characteristics of three cycle slip detection ways including high order difference method,phase reduce pseudo orange law method and ionized layer remnant method were studied in detail buy using measured data.The analysis results show that the ionized layer remnant method is suitable for the small cycle slip detection,phase reduce pseudo orange law method and ionized layer remnant method is suitable for the big cycle slip detection and the former detection effect is better;a combination of several methods will be required in order to better complete the cycle slip detection.The research results are helpful to improve the accuracy of GPS baseline solution,and facilitate the development of the corresponding software.
