Search and rescue positioning terminal and method based on AIS and Beidou navigation satellite system

Abstract

The invention provides a search and rescue positioning terminal based on an AIS and a Beidou navigation satellite system. The search and rescue positioning terminal comprises a core processing module, a GNSS module, an AIS transmitter module and a Beidou short message receiving and dispatching module. The core processing module is used for controlling the work of the search and rescue positioning terminal. The GNSS module is connected with the core processing module and used for positioning the search and rescue positioning terminal through a satellite so as to acquire positioning data. The AIS transmitter module is connected with the core processing module and used for packaging the positioning data into standard AIS information to be emitted. The Beidou short message receiving and dispatching module is connected with the core processing module and used for packaging the positioning data into a Beidou short message to be emitted. The invention further provides a search and rescue positioning method based on the AIS and the Beidou navigation satellite system. According to the search and rescue positioning terminal and method based on the AIS and the Beidou navigation satellite system, the AIS and the Beidou navigation satellite system are combined to be used according to personal aquatic search and rescue, the problems of long-distance and short-distance continuous warning and positioning search and rescue are effectively solved, and the search and rescue efficiency is improved.

Description

technical field [0001] The present invention relates to a search and rescue positioning terminal and a search and rescue positioning method, specifically to a search and rescue positioning terminal based on an automatic identification system (AIS, Automatic Identification System) and a Beidou satellite navigation system (referred to as Beidou, BDS, BeiDou Navigation Satellite System) The invention relates to a method and belongs to the technical field of water search and rescue positioning and communication navigation, and is particularly suitable for water distress alarms and position positioning reports. Background technique [0002] At present, the maritime search and rescue positioning and communication devices used in the prior art are mainly based on the global satellite search and rescue system COSPAS-SARSAT system and the Personal Locator Beacon (PLB, Personal Locator Beacon) in the GPS / GLONASS system, emergency radio position indicating EPIRB (Emergency Position Ind...
