Abstract In order to solve the problem that small cycle slips can not be detected with difference method, the method with oneclass support machine combined with phase reconstruction theory is proposed to detect the cycle slips in differential GPS carrier phase series. The method is based on the principle and algorithm of mining outlier data with oneclass support machine.A cycle slip detection experiment of practical observations indicates that cycle slips as small as 0.5 cycles can be detected by using oneclass support machine. The method is applicable under dynamic situations as well as static situations. Furthermore, it is applicable to single frequency GPS receiver.
Key words ：
