Research on Shadow Matching Algorithm Based on Consistency Probability Weighting

Shadow matching method can effectively improve the positioning accuracy of street crossing direction in urban canyons. This paper discusses the selection method of search area where the matching initial positioning point is not too accurate. Aiming at the problem of insufficient positioning along the street, this paper discusses the matching method of satellite signals with fuzzy direction range along the street. On the basis of clustering shadow matching, the user's position is finally determined through the weighted solution of different scores.
