Abstract
Aspects of the disclosure provide a method for multi-path interference detection. The method includes receiving, by a positioning device, a satellite signal transmitted from a satellite. The satellite signal carries a ranging code. Further, the method includes locking an internal code generated by the positioning device to the ranging code, determining characteristics of correlations between the satellite signal and the internal code with different time shifts, and detecting satellite signal deterioration due to multi-path interference based on the characteristics of the correlations between the satellite signal and the internal code with different time shifts.
