Ocean satellite data broadcasting system and method

Abstract

The invention discloses an ocean satellite data broadcasting system and an ocean satellite data broadcasting method. The system comprises a ground master control station, a bidirectional small station, a one-way receiving small station, a Beidou system and an information application system, wherein the ground master control station is used as a communication core of a whole data broadcasting system, for collecting, accessing, processing and releasing forward release information and collecting return information; the bidirectional small station can perform bidirectional service interaction with the master control station via a communication satellite; the one-way receiving small station is used as a communication terminal of the whole system, being responsible for receiving satellite broadcast information, and meanwhile receiving Beidou positioning information and a short message, and providing on-demand broadcasting and posting back of information via a Beidou link; the Beidou system provides a posting back link before data information transmission; and the information application system is responsible for restoring the satellite broadcasting data received by a remote terminal to information can be used by a user, gathering feedback information, achieving access of each service sub-system and managing terminal information. According to the system and the method provided by the invention, wide-area and efficient information broadcasting distribution capacity and a safety authorization mechanism are achieved, and conditional receipt of ocean remote sensing data is also achieved.

Description

technical field [0001] The invention relates to a communication field, in particular to a marine satellite data broadcasting system and method. Background technique [0002] At present, my country's satellite communication usually uses several major foreign satellite communication system products such as Inmarsat, Thuraya, and Iridium. Although the communication quality is high, they all belong to narrow-band communication, the transmission rate is low, and multimedia, etc. cannot be realized. High-speed communication business. At the same time, the high cost of after-sales maintenance of foreign products and the time lag are difficult problems to solve. [0003] Compared with foreign countries, the level of domestic satellite communication technology is far behind, especially in the civil satellite system and application technology, the country is still in its infancy. Over the years, domestic satellite applications, including satellite telephones, satellite broadcasting, ...

AI Technical Summary

Problems solved by technology

The satellite communication system independently developed by our country can basically meet the needs of the military, but there is no mature commercial satellite communication system solution in the civilian market, which is in stark contrast to the huge domestic market demand
