Description

Sky-ground-sea integrated communication system based on broadband satellite and implementation method

Technical Field

The present invention relates to the field of Internet technology, and in particular to a broadband satellite-based sky-ground-sea integrated communication system and an implementation method thereof.

Background Art

Conventional marine communication networks mainly include marine wireless communication systems, marine satellite communication systems, and shore-based mobile communication systems based on land cellular networks. Due to the incompatibility of the communication modes of these communication systems, the different communication bandwidths, the blind spots in coverage, and the lack of an efficient and unified management mechanism, conventional marine communication networks are increasingly unable to meet the growing requirements for marine data transmission and marine communications. At present, some countries have proposed the concept of an integrated marine communication network, where ships/buoys near the coast are connected to ground-based dedicated base stations or cellular base stations through marine wireless links, and ships/buoys in the open sea are connected to marine communication satellites through satellite links. Finally, an effective marine communication network is formed through satellites and ground base stations to ensure stable and efficient communication services at sea. my country's land public mobile communication system has developed extremely rapidly. In the nearshore area, shore-based 4G mobile communication systems can be used as a supplement to marine wireless communication and satellite communication. At the same time, my country uses the Beidou satellite navigation system and the marine satellite communication system as a means of offshore communication, but there is no good means of integrating communication between satellites, drones, shore-based, and ships.

The existing marine communication systems are isolated from each other and lack a unified coordination and management mechanism, which cannot guarantee full coverage, low cost, and high-speed transmission of marine communications. The shore-based wireless communication system has the disadvantages of limited coverage, inability to cover offshore communications, and limited communication distance; the satellite communication system can provide stable communication services covering the offshore all day and all day, but the disadvantage is high cost, and there are also problems such as information security; marine wireless communication systems, such as medium frequency, high frequency, very high frequency systems and ship automatic identification systems AIS, have the disadvantage of low data transmission rate. At the same time, as the communication distance increases, the data transmission rate becomes lower and lower, and the communication distance is limited, making it impossible to provide long-distance, full-coverage marine communication services.

Summary of the invention

In view of the above problems, the present invention proposes an integrated sky, land and sea communication system based on broadband satellite and an implementation method. Based on the development status and trend of broadband satellite communication transmission networks and air, land and sea information transmission networks, an integrated sea, land, air and space self-organizing communication system combining multi-dimensional heterogeneous data transmission networks such as satellite data transmission networks, air information networks, sea surface information networks and coastal information networks is proposed to ensure the effective return of marine videos, pictures and other data, and provide an effective means for communication transmission such as marine emergency monitoring and emergency accident rescue.
