Problems solved by technology

There are many factors hindering the popularization of satellite communication. One of the most important reasons is that the satellite communication system is an independent communication system, and the data services carried by it are very limited, which cannot properly meet the information needs of users.

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1As shown, the multi-data service implementation system of the present invention is established on the basis of the existing satellite communication system. The system of the present invention includes a business service center, several user terminals and a satellite communication system. Among them, the satellite communication system includes one or more satellites and one or more ground receiving centers. The satellite acts as a relay station in the air, that is, the electromagnetic waves sent by the ground receiving center are amplified and then sent back to another ground receiving center or authorized user terminal, etc. The ground receiving center is the interface between the satellite system and the ground public network, and the ground users enter and exit the satellite system through the ground receiving center to form a link....

Abstract

The disclosed satellite communication based multiple data business system comprises: a business service center, including a data business interface connecting and receiving business data from all data business gateways and the ground receive center, a data storage unit, a protocol frame package / analysis unit packing former data and inserting into data segment in protocol frame, and a signal transmission unit conversing packed protocol frame into satellite signal for transmission; some user terminal, and gateways for connection. This invention frees to geographical condition limit.

Description

technical field [0001] The invention relates to a multi-data service system, in particular to a multi-data service system based on a satellite communication system. Background technique [0002] Satellite communication refers to the communication between two or more ground receiving centers using artificial earth satellites as relay stations to forward or reflect radio signals. The satellite communication system has the advantages of global coverage, fixed broadcast capability, flexible allocation of bandwidth on demand, and support for mobility. It is the best candidate for providing data services to users distributed around the world. If a satellite communication system is well designed and can cover the entire earth's surface, it is very suitable, even the only choice, for aviation and marine users and users in remote areas who lack ground communication infrastructure. Even in areas with dense wired networks, satellite communications can serve as an alternative to increa...
