Sea-land communication system based on Beidou satellite

Abstract

The invention discloses a sea-land communication system based on the Beidou satellite. The sea-land communication system based on the Beidou satellite comprises a ship-borne terminal, the Beidou satellite, a data communication server and a land user side. Data are collected and processed by the ship-borne terminal which is communicated with the Beidou satellite. The received data are processed by the Beidou satellite and forwarded to the data communication server or the ship-borne terminal through the Beidou satellite. The received data are processed, or stored or forwarded to the land user side through the data communication server or sent to the ship-borne terminal through the Beidou satellite. The land user side is connected with the data communication server through the internet so as to receive short message data forwarded by the data communication server or send the short message data to the data communication server. Information is forwarded through the data communication server and convenient communication between a user on a ship and a user on the land can be achieved, so that the communication condition between the users is effectively improved.

Description

technical field [0001] The invention relates to the technical field of Beidou satellite communication, in particular to a land-sea communication system based on Beidou satellite. Background technique [0002] With the rapid development of modern society, satellite communication systems play an increasingly important role in meteorology, petroleum, forest fire prevention, disaster forecasting, transportation, public security and other special industries, which can be said to be closely related to our lives. Especially in the maritime field, it plays a particularly important role. Since there is neither wired network coverage nor base station signals on the ocean, ships can only communicate with the outside world (including ships on land and on the sea) through satellites. The Beidou satellite developed by my country can provide positioning, navigation and short message communication services for the marine and maritime fields. [0003] The Beidou satellite navigation system...

AI Technical Summary

Problems solved by technology

At present, ship users and land users communicate based on Beidou satellites, and can only be forwarded through Beidou satellite transceiver antennas. This requires land equipment to also have antennas, and the communication objects are limited. The cost of setting up satellite antennas is high, which is not conducive to the promotion of sea-land communications.
