针对电离层总电子含量变化率( TECR)方法和双频码相组合( MW)方法探测周跳各自的局限性，综合利用TECR法和MW法进行周跳探测。首先采用TECR法探测周跳，然后用MW法进行第2次探测，最后综合电离层TECR法和MW法的宽巷模糊度探测L1频率和L2频率上发生的周跳。这种综合探测法不受接收机与卫星间的几何距离、接收机钟差和卫星钟差、电离层折射的影响。采用实测数据进行试验，结果表明，综合利用TECR法与MW法探测GPS周跳比采用单一方法探测周跳更加有效、可靠。
針對電離層總電子含量變化率( TECR)方法和雙頻碼相組閤( MW)方法探測週跳各自的跼限性，綜閤利用TECR法和MW法進行週跳探測。首先採用TECR法探測週跳，然後用MW法進行第2次探測，最後綜閤電離層TECR法和MW法的寬巷模糊度探測L1頻率和L2頻率上髮生的週跳。這種綜閤探測法不受接收機與衛星間的幾何距離、接收機鐘差和衛星鐘差、電離層摺射的影響。採用實測數據進行試驗，結果錶明，綜閤利用TECR法與MW法探測GPS週跳比採用單一方法探測週跳更加有效、可靠。

In order to overcome the shortcomings of the ionospheric total electron content rate ( TECR) and dual-frequency code phase combination ( MW ) methods, a combination of the two methods was used for cycle slip detection. First, the TECR method was used to detect the cycle slip. Then, the MW method was used to detect the cycle slip for the second time. Finally, the ionospheric TECR and the wide lane ambiguity of MW were used together to detect the cycle slip on L1 and L2 frequencies. This combined method was not affected by the geometrical distance between the receiver and satellite, the receiver clock offset, the satellite clock offset, and ionospheric refraction. According to the test results of measured data, the TECR and MW combined method is more effective and reliable than a single method in detecting GPS cycle slip.
