Satellite short message sending and receiving device and method

Abstract

The invention discloses a satellite short message sending and receiving device and method which are characterized in that based on an Inmarsat D+ system, short messages are edited, output and input by a smart phone with the function of Bluetooth communication; the output and input short messages are converted by a data repeater according to an Inmarsat D+ system communication protocol, and then transmitted to a satellite terminal of the Inmarsat D+ system; and a data storage module is arranged between the satellite terminal and the data repeater so as to ensure the safety and stability of data. The device provided by the invention has the advantages that the Inmarsat D+ system is installed conveniently without connecting cables at a long distance; through Bluetooth wireless transmission, the butt joint and matching problems of interfaces are avoided, namely, the problem that the data transmission interfaces are difficult to match is solved, and the wireless transmission process is artificially operated on the smart phone and can be operated movably, which highlights the convenience of the device; and all downlink information and data of the Inmarsat D+ system are stored by the data storage module, thereby ensuring the no loss of data and the stability of the sending and receiving data.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a satellite short message sending and receiving device and method. Background technique [0002] The Inmarsat-D+ system is the first two-way satellite short message transmission system based on seamless coverage of maritime satellites. The system consists of four parts: ① Inmarsat maritime satellites; ② Satellite ground receiving station (LES); ③ User network command center (UCO) ; ④ remote terminal or mobile terminal (MES). The system supports low-rate two-way information and data services, enabling users to use Inmarsat-D+ remote terminals or mobile terminals anywhere in the world to communicate with other terminals in the Inmarsat-D+ system or the user network command center for two-way short message communication. The Inmarsat-D+ satellite terminal has a built-in GPS receiver, which can report its position at any time. The digital interface of the Inmarsat-D+...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a method and device for installing Inmarsat-D+ satellite terminals on ships and vehicles to realize wireless stable transmission of Inmarsat-D+ satellite short messages, and to solve the problem of editing short messages in the environment of bumps and shocks inside vehicles and ships. Inconvenient, difficult to match the data transmission interface, and unstable sending and receiving data, better realize the application of the two-way satellite short message function of the Inmarsat-D+ system in the field of ship and vehicle tracking and monitoring
