The individual characteristics of the AIS and satellite electronic information are analyzed, and proposes a track correlation algorithm of AIS and satellite electronic information based on point-track distance, aiming at the problem of low positioning accuracy, strong noise and discontinuous of satellite information. First, the satellite electronic information is clustered with attribute and filtered with speed threshold, then calculate the distance between the two kinds of track after time adjustment. Constructing bipartite weighted graph of distance matrix to solve the optimal match problem at last. Simulation shows the effectiveness and applicability of the method.
