An object of an example embodiment of the present disclosure is to stably estimate a navigation status of a target ship at a predetermined time from time-series position information of the ship. A ship behavior analyzing device according to the example embodiment of the present disclosure includes a ship detection means for detecting a ship from synthetic aperture radar data, a wake extraction means for extracting a wake of the detected ship, a wake pattern generation means for generating a wake pattern image by using the extracted wake, and a navigation status estimation means for estimating a navigation status of the target ship by using the generated wake pattern image.

An unmanned aircraft system of an unmanned aircraft, a control system arranged on a marine vessel, as well as a method for controlling a navigation system of a marine vessel is described. This may enable improved operation of the marine vessel in docking situations at a mooring position.

The system accepts an operation to be carried out to virtually install installation objects on a water surface, acquires positional information about each point, and creates course data of a course passing through areas to be determined on the basis of installation positions of the installation objects in the order of installation. The system installs installation objects as buoys, creates a guide image to be used to indicate a buoy to be passed next and a direction from the buoy to be passed next to a buoy to be passed further next by using the course data while intending the guide image for a user of a boat configured to travel along the course on the water surface, and displays the created guide image on a display unit arranged on a hull of the boat.

A satellite Automatic Identification System (AIS) is for tracking a plurality of maritime vessels. The AIS may include a ground AIS server and a constellation of Low-Earth Orbit (LEO) satellites in communication with the ground AIS server. Each LEO satellite may include an AIS payload configured to receive AIS messages from the plurality of maritime vessels and determine therefrom reported vessel position data, determine actual signal arrival measurements for the AIS messages, and determine a potential spoofing maritime vessel based upon the reported vessel position data and actual signal arrival measurements and send a potential spoof alert to the ground AIS server. The ground AIS server may be configured to perform time sequenced pairwise differential calculations of the actual signal arrival measurements from at least one of the AIS payloads and for the potential spoofing maritime vessel to estimate a position of the potential spoofing maritime vessel.

According to the present invention, a route controller generates a route that makes a ship dock at a berthing facility. The route includes a first location and a second location (P2). The first location is a via point that is offset a prescribed distance in a direction that is orthogonal to the direction in which the berthing facility is oriented from a docking point for the ship at the berthing facility. The second location is the docking point for the ship at the berthing facility. The first location is immediately before the second location in the sequence to be realized by the ship. The route is generated such that the ship remains oriented in the direction in which the berthing facility is oriented as the ship moves from the first location to the second location.
