Abstract

Inertial information has been proposed to improve the success rate and repair rate for BDS triple-frequency cycle-slip detection in severe environment with multipath effects.At the same time, a BDS/INS loose coupled model has been developed. An innovative INS aided BDS triple-frequency combination method was developed which based on the traditional method of code-phase combination and geometry-free linear combination. The INS aided cycle-slip detection monitoring value was established and the effect of INS positioning error on cycle-slip capacity was analyzed. The proposed method overcomes the shortcoming of cycle-slip detection capacity influenced by the pseudorange observation precision. It also realizes small cycle-slips detection for BDS in severe multipath effects environment. At last, a field test was analysised with INS/BDS triple-frequency integrated positioning system onboard. The results indicate that the method proposed in this paper shows a high cycle-slip detection success rate and repair rate, when traditional triple-frequency detection model losed efficacy above water surface with multipath effects, and it also can be effective in low frequency sampling data.

Key words： multipath effects; BDS; inertial aided; loose coupling; cycle-slip detection
