specific Embodiment

[0055] A specific embodiment of the present invention is as follows:

[0056] Such as Figure 5 As shown, set No. 1 shore-based AIS base station 31, No. 2 shore-based AIS base station 32 and No. 3 shore-based AIS base station 33 as three shore-based AIS base stations in the shore-based AIS base station network; offshore airship 34 and ocean-going airship 35 are The two airships in the airship network; No. 1 ocean-going ship 36 and No. 2 ocean-going ship 37 are two ocean-going ships sailing in the ocean. according to Figure 3-4 The process shown is firstly the layout and positioning of the airship network. The offshore airship 34 can receive the transmissions from the three shore-based AIS base stations No. 1, No. 2, No. 2 and No. 3. According to the ITU-R M.1371-4 standard, the specific location information of the corresponding three shore-based AIS base stations can be obtained by analyzing the AIS message 4 message of the shore-based AIS base station, and then by measurin...

Abstract

The invention discloses a self-organizing ship positioning system based on an airship and a positioning method thereof. The positioning system comprises an airship positioning and control terminal and a ship positioning terminal, wherein the airship positioning and control terminal comprises an airship wireless transmitting and receiving module, an AIS base station module, an airship control module and an airship main control module; and the ship positioning terminal comprises a ship wireless transmitting and receiving module, an AIS ship station module, a display module and a ship main control module. The airship is used for carrying the AIS base station, through reasonable layout and planning, the airship and a shore-based AIS base station communicate, and positioning of the airship is realized through accurate position information of the shore-based AIS base station; then, the laid airship network is used for covering ocean ships, the ships directly communicate with the airship, and thus, self-organizing positioning of the ocean ships is thus realized; and in comparison with an individual shore-base AIS base station network, the positioning distance of the invention is farther, and self-organizing positioning of the ocean ships can be realized through a land-based navigation system.

Description

technical field [0001] The invention relates to the field of navigation and positioning, in particular to a self-organizing positioning method for ocean-going ships. Background technique [0002] In order to ensure the safety of the ship's navigation, the ship should be equipped with an air-based and land-based dual backup positioning and navigation system. At present, the space-based navigation system mainly relies on GNSS (Global Satellite Navigation System), and the navigation system that uses AIS (Automatic Ship Identification System) to realize the autonomous positioning of ships has become one of the best candidates for IMO to force the ground-based navigation system. However, due to the limitations of shore-based base stations and the limitation of ship distance, land-based positioning cannot be realized for non-shore ships or ships that are not positioned around. For example, the Chinese patent ZL201110133252.8 discloses "An AIS Ship Autonomous Positioning and Navig...
