Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a 1m2 back-feeding type full-automatic portable emergency satellite communication satellite communication system. Background technique [0002] With the rapid development of economy and society, there are more and more emergencies around the world, and they are becoming more and more frequent. The emergency response requires fast and effective. The conventional communication on site has been destroyed or paralyzed, and the rapid transportation can no longer reach the site. , satellite communication is not restricted by the geographical environment, and the portable satellite communication earth station can be moved by a single person to the scene where people can enter, and the satellite communication link can be quickly established; the amount of communication information for emergency on-site disposal is generally relatively large, in order to ensure two-way mult...
