Intelligent terminal based on Tiantong satellite communication

Abstract

The invention discloses an intelligent terminal based on Tiantong satellite communication, and the terminal comprises an application processing module, a Tiantong module and a positioning navigation module; a radio frequency front-end module used for being connected with a satellite antenna is arranged in the Tiantong module, and the radio frequency front-end module is used for transmitting a radio frequency signal received or sent by the satellite antenna to the Tiantong module; the Tiantong module is connected with the application processing module, the Tiantong module comprises a baseband processing unit, a radio frequency processing unit and a power management and interface unit, the baseband processing unit is connected with the radio frequency processing unit, and the baseband processing unit is used for processing a radio frequency signal and operating a Tiantong standard protocol and physical layer software to realize access of a Tiantong network; the radio frequency processing unit is used for receiving and transmitting radio frequency signals and comprises a radio frequency receiving and transmitting chip controlled by the baseband processing unit, and the radio frequency receiving and transmitting chip is connected with the radio frequency front-end module. According to the invention, normal communication can be carried out in a severe working environment and an area which cannot be covered by a ground network, and the coverage is wide.

Description

Technical field [0001] The present invention relates to the field of radio frequency signal processing, and more particularly to a smart terminal based on Tiantong satellite communication. Background technique [0002] The exhibition of the existence of the ground mobile communication network in the remote area of ​​the ocean and population is unable to cover. Tiantong No. 1 Satellite Mobile Communication System is a satellite mobile communication system, which is independently developed by China. It consists of spatial sections, ground segments and user terminals. It belongs to GEO satellites, located 30,000 kilometers over the equator and is relatively stationary with Earth, by point beam The way covers the ground, and can provide communication capabilities in areas where mobile communications systems such as fields, oceans, etc., mainly providing voice, SMS, and packet data services. Therefore, in the departments of fisheries, geological exploration, border defense, forestry a...

Problems solved by technology

However, for many places where the ground network cannot be covered or where 2G / 3G / 4G communication equipment cannot communicate with the network, Internet communication cannot be carried out. Therefore, the use of ground network and 2G / 3G / 4G network communication is very limited and the coverage is not wide.
