摘要
在GPS进行观测时,由于物体遮挡、电离层异样等因素导致卫星信号在短时间内出现一种失锁行为,导致误差过大,影响定位精度。为了解决这一问题,本研究利用MATLAB软件,根据双频码相组合法和电离层残差法的特点,对GPS载波相位观测值进行周跳探测,结果表明:此方法可以准确探测出人为加入的周跳。
During GPS observation, satellite signals show a kind of lock-out behavior in a short period of time due to object occlusion, ionospheric anomalies and other factors, resulting in large errors and affecting positioning accuracy. In order to solve this problem, this paper uses MATLAB software, according to the characteristics of dual frequency code phase group method and ionospheric residual method, to detect the cycle jump of GPS carrier phase observation value, the results show that this method can accurately detect the man-made cycle jump.
