Abstract As is known, it is not an easy thing to capture the precise Pcode for most of the receivers and only the cross correlated Pcode could be derived. With such cross correlated PCode, the detecting and repairing capability of the traditional combinations, the (1,-1) and (-7,9), will be out of one cycle level. To resolve the problem, an improved method which takes the multipath effect of the pseudo range into account is proposed to upgrade the cycle slip repairing capability of the aforementioned combinations. The experiment shows that the new method can remove the epochwise multipath effect of the pseudo range and repaire successfully cycle slip within one cycle level.
