Emergency lifesaving communication method based on multi-beam communication satellite

Abstract

The invention discloses an emergency lifesaving communication method based on a multi-beam communication satellite. The emergency lifesaving communication method comprises the specific steps that a person in distress obtains self positioning information through a satellite handheld terminal carried by the person; the satellite handheld terminal carried by the person in distress forms distress alarm information and sends a distress survival signal; the rescue station satellite communication equipment automatically forwards the signal to a remote terminal of a rescue department; the rescue department forms alarm confirmation information and sends the alarm confirmation information to the rescue station satellite communication equipment through the remote terminal; and after receiving the alarm confirmation information, the rescue station satellite communication equipment automatically forwards the alarm confirmation information to the satellite handheld terminal of the person in distress, and the two parties transfer to rescue communication. Special channel resources are reserved for emergency communication, rapid transmission of distress survival messages can be effectively guaranteed, alarm signals are processed in an automatic guarding mode, the processing and forwarding speed is guaranteed, and it is guaranteed that long-distance alarm, positioning and communication can be rapidly carried out.

Description

technical field [0001] The invention belongs to the field of satellite mobile communication, in particular to the technical field of emergency lifesaving communication in the field of satellite mobile communication. Background technique [0002] The satellite communication system has the characteristics of large coverage, limited by terrain, and low dependence on ground fixed facilities. Under the conditions of natural disasters such as floods and mudslides, establish connections with mobile satellite communication equipment such as ground satellite handheld terminals to provide important communication guarantees for emergency lifesaving. When a disaster occurs, how to quickly and effectively realize the information transmission between the satellite handheld mobile communication terminal and the rescue department, and provide the rescue department with the necessary rescue information in time is one of the key problems to be solved in the satellite emergency life-saving com...
