Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] figure 2 An embodiment scenario of the present invention is illustrated.

[0030] 201 and 202 are two AIS shore stations, 213 and 214 are two AIS ship stations, 220 is an AIS shore station network center with position detection function, and 237 is a GNSS satellite, which can provide GNSS signals for the ship station so that the ship The station's GNSS receiver solves the correct position and provides it to the AIS ship station. 245 and 246 are respectively the false positions that the AIS ship station 213 may broadcast. The specific processing steps of location information anti-spoofing detection are as follows:

[0031] 1) Distance detection mode

[0032] The AIS ship stations 213, 214 are within the receiving range of the AIS shore stations 201, 202, can receive the AIS signals of the ship stations 213, 214, and analyze the GNSS position ...

Abstract

The invention belongs to the field of ship navigation, and relates to an automatic identification system (AIS) position information anti-spoofing method based on a Ranging Mode (R-mode). By transplanting the ranging technology of the AIS ship station to the AIS shore station, R-mode ranging and positioning functions are added for the AIS shore station, and the correctness of the location information sent by the AIS ship station is detected through two steps of a distance detection mode automatically completed by the shore station and a position detection mode completed by the network center ofthe AIS shore station to realize the anti-spoofing function of the AIS location information, thereby preventing malicious spoofing, effectively protecting the navigation safety of ships, and improving the water safety supervision capability.

Description

technical field [0001] The invention belongs to the field of ship navigation, relates to the detection of spoofing of automatic identification system (Automatic Identification System-AIS) position information, and specifically proposes an anti-spoofing method for AIS position information based on an R-mode. Background technique [0002] In order to ensure the safe navigation of ships, the International Maritime Organization (IMO) regards Position, Navigation and Timing (PNT) information as the strategic cornerstone of e-navigation development. The Global Navigation Satellite System (GNSS) is currently the most important source of PNT information in the field of maritime navigation, providing information for ship station equipment such as AIS and Electronic Chart Display and Information System (ECDIS). location information. [0003] AIS is a communication and navigation system equipped by IMO mandatory shore stations and ship stations, which plays an important role in ensuri...
