Abstract:
To solve the problem that the observation conditions in the continuously operating reference station net(CORSNet)are complex and often appear cycle slips, a classified least-square cycle-slip repair algorithm is presented. First, the common cycle-slip detection method is used to determine the satellites with cycle slip and their frequencies. Then, the error equation composed by the measurement values of un-reference satellites with non cycle slips is used to estimate the real-time position of the rover stations and the cycle slips of the reference satellite. The estimated parameters are substituted into the error equation composed by the measurement values of reference satellites with cycle slips. The cycle slips of un-reference satellites can be obtained from the modified values of the later error equation, realizing the real-time position and the repair of the cycle slips of the rover stations. The experimental results show that this algorithm can repair the cycle slips and obtain accurate real-time positions when the cycle slips of several satellites appear at the same time. The problem of the breakdown contamination rate caused by the cycle-slip repair by the robust estimation method is effectively avoided.
