SYSTEM AND METHOD FOR TRACKING AND FORECASTING THE POSITIONS OF MARINE VESSELS

摘要

There is disclosed a system and method for forecasting the positions of marine vessels. In an aspect, the present system is adapted to execute a forecasting algorithm to forecast the positions of one or a great many marine vessel(s) based on one or more position reporting systems including coastal and satellite AIS (S-AIS) signals or LRIT received from the vessel. The forecasting algorithm utilizes location and direction information for the vessel, and estimates one or more possible positions based on previous paths taken by vessels from that location, and heading in substantially the same direction. Thus, a body of water can be divided into “bins” of location and direction information, and a spatial index can be built based on the previous paths taken by other vessels after passing through that bin. Other types of information may also be taken into account, such as ship-specific data, nearby weather, ocean currents, the time of year, and other spatial variables specific to that bin.

主权项

1. A computer-implemented system for forecasting the position of a marine vessel based on one or more position reports, the system adapted to:
provide, for a body of water, a spatial index comprising a plurality of bins, each bin containing location and direction information specific to each bin; obtain one or more position reports for a vessel comprising position and direction information; determine one or more bins the vessel has travelled through, and execute a forecasting algorithm based on the spatial index and the location and direction information specific to the one or more bins through which the vessel has travelled.
