Description

technical field [0001] The invention relates to the technical field of radio frequency signal processing, in particular to a terminal based on Tiantong satellite broadband data communication. Background technique [0002] Our country has a vast territory, and there are situations where ground mobile communication networks cannot cover places such as oceans and sparsely populated remote areas. Tiantong-1 satellite mobile communication system is a satellite mobile communication system independently developed and constructed by China. It is a GEO satellite composed of space segment, ground segment and user terminal. It is located 30,000 kilometers above the equator and is relatively stationary with the earth. It can cover the ground by means of ground, and can provide communication capabilities in areas that cannot be covered by ground mobile communication systems such as the field and the ocean, and mainly provide users with voice, short message and packet data services. Ther...

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.
