Big-dipper satellite-signal civil processing system

Abstract

The system includes interface message processor of satellite, kernel processor, public network interface, terminal of big dipper satellite. The kernel processor includes queue reception module, message preprocessing module, message distribution module, common module, service process module, module for receiving data queue. The service process module can process data in different types, and convert them to commercial format, and the processed data through public network gateway are transferred to final users. The invention realizes bidirectional data transmission between terminals of big dipper satellite and users on public network. Advantages are: raising security of data greatly, lowering communication cost, displacing and decomposing burden generated after navigation system of big dipper satellite opens to uses on public network.

Description

technical field [0001] The invention relates to a civilian processing system for Beidou satellite signals. Background technique [0002] The Beidou satellite navigation system is a satellite navigation system with my country's independent intellectual property rights. It is also commonly referred to as "Beidou-1 satellite navigation system", and is referred to as "Beidou satellite navigation system" in the present invention. [0003] The system similar to the Beidou satellite navigation system is mainly the Global Positioning System (GPS, Global Positioning System) of the United States, but because GPS is a passive positioning system, it does not have data communication functions. The existing global communication system can only rely on the maritime satellite system established abroad to achieve global communication without blind spots. However, although maritime satellites can transmit data, they do not have positioning functions, and they communicate through foreign telep...

[0003] The system similar to the Beidou satellite navigation system is mainly the Global Positioning System (GPS, Global Positioning System) of the United States, but because GPS is a passive positioning system, it does not have data communication functions

The existing global communication system can only rely on the maritime satellite system established abroad to achieve global communication without blind spots. However, although maritime satellites can transmit data, they do not have positioning functions, and they communicate through foreign telephone systems, which cannot guarantee communication security and use costs. high

[0004] The Beidou satellite navigation system is an active positioning system. Therefore, the Beidou satellite navigation system has both positioning functions and data communication functions. However, due to the inability to connect to the public network, the Beidou satellite navigation system has not been able to realize civilian use.
