Description

technical field [0001] The invention discloses a Sub-G frequency band marine emergency call system, which belongs to the technical field of emergency rescue. Background technique [0002] With the advancement of technology and the strengthening of marine awareness, my country has invested more and more in marine development, and various economic activities have been actively carried out. At the same time, marine activities are also a high-risk industry. Due to the fact that the production process is far from the inland, the natural environment is volatile, and the sea area is huge, etc., all of which make rescue work extremely difficult in the event of a sudden disaster. How to accurately find the trapped people has become a very important task when they are far away from the inland and the traditional means of communication are limited. [0003] At present, most of the solutions for emergency communication in the existing technology are through satellite communication, or ...
