Space-based search and rescue transceiver terminal

Abstract

The invention discloses a space-based search and rescue transceiver terminal. The terminal comprises an AIS receiver module, a Lora transceiver module, a Beidou short message transceiver module, a processor module, a distribution module, a VHF-band receiving antenna, a UHF-band receiving antenna, a UHF-band sending antenna and an S-band receiving antenna. The processor module is connected with theAIS receiver module, the Lora transceiver module, the Beidou short message transceiver module and the distribution module. The AIS receiver module is used for receiving and analyzing ground AIS rescue information. The Lora transceiver module is used for receiving and analyzing ground Lora system rescue information. The Beidou short message transceiver module is used for receiving and analyzing Beidou short message rescue information. The processor module processes a plurality of analysis results into standardized format information. The distribution module sends the standardized format information to a ground rescue command center. The space-based search and rescue transceiver terminal can unify the rescue information under different search and rescue systems into standardized format information and issue the standardized format information.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a space-based search and rescue transceiver terminal. Background technique [0002] Due to the wide coverage of satellite sending and receiving signals, and the wireless connection of the satellite-ground link, there is no need for large-scale ground station deployment, and it is not subject to geographical restrictions. Satellite-based space-based search and rescue systems are widely used in various search and rescue missions. [0003] The existing space-based search and rescue systems mainly include the global satellite search and rescue system (COSPAS / SARSAT), the search and rescue system based on AIS (Automatic Identification System, ship automatic identification system), the search and rescue system based on Lora (LongRange Radio, long-distance radio) and the search and rescue system based on Beidou satellite search and rescue system. Among them, the AIS-bas...

Problems solved by technology

[0004] However, the existing search and rescue system includes many different search and rescue systems such as AIS, Lora, and Beidou short message. In order to ensure that the rescue command center and rescue forces can accurately receive rescue signals under multiple different search and rescue systems, multiple The terminals corresponding to different search and rescue systems will increase the carrying burden of rescuers and affect rescue efficiency; at the same time, the deployment of multiple different terminals will also lead to increased search and rescue costs.
