Problems solved by technology

However, in many cases, limited by the layout of AIS shore station reference points, there are no positioned ship stations around the ship that can be used as mobile reference points. For example, AIS ship statio

Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0053] figure 2 An embodiment scenario of the present invention is illustrated.

[0054] 201 and 202 are two AIS shore stations, and 213, 214 and 215 are three AIS ship stations. According to the propagation distance of the AIS signal, the ship stations 213 , 314 , and 315 can only receive signals from the two AIS shore station reference points 201 and 202 . 213, 214, and 215 constitute a cooperative ship station group, 213 is the master cooperative ship station, and 214 and 215 are slave cooperative ship stations. The slave cooperative ship stations 214 and 215 share the ranging information 2241 , 2242 , 2251 and 2252 between the ship and shore under the ship-shore information cooperation request of the master cooperative ship station 213 . The slave cooperative ship station 214 shares the ship ranging information 2245 with the slave cooperative sh...

Abstract

The invention relates to a two AIS (automatic identification system) reference point-based ship self-organization cooperative localization method and belongs to the ship localization and navigation field. According to the two AIS (automatic identification system) reference point-based ship self-organization cooperative localization method, steps such as localization mode discrimination, information data preparation, self organization coordination, localization equation solving and localization information sharing are adopted, and the above processes are repeated, ship-shore and ship collaborative information is constantly updated, so that the dynamic localization of all cooperative ships in a cooperative ship station group can be realized; under a condition that only two AIS shore stations are adopted as localization reference points, and traditional ranging and localization requirements are not satisfied, based on self-organization coordination between ships and stations, the shearing of ranging information between ships and shores as well as between ships can be realized, and the self-organization localization of cooperative ship stations can be realized; and extra AIS shore stations are not required to be adopted, the self-organization cooperative localization of coastal ships can be realized, and therefore, the application range of an AIS ranging and localization system can be greatly extended.

Description

technical field [0001] The present invention relates to a ship self-organization cooperative positioning method with two AIS reference points. A method for self-organizing cooperative positioning belongs to the field of ship positioning and navigation. Background technique [0002] AIS is a communication and navigation equipment that ships are required to equip according to the International Convention for the Safety of Life at Sea. The AIS equipment installed on coastal ports is called AIS shore station, and the AIS equipment installed on ships is called AIS ship station. But the positioning and navigation information in the existing AIS system completely depends on the position provided by the Global Navigation Satellite System (GNSS) receiver. In order to ensure safe navigation, the International Maritime Organization (IMO) advocates that ships in the future should be equipped with dual backup positioning and navigation systems based on space and land. Therefore, IMO ha...
