Novel dismounting-free portable satellite communication antenna terminal

Abstract

Provided in the invention is a novel dismounting-free portable satellite communication antenna terminal comprising an azimuth assembly, a pitch assembly, a polarization assembly, a folding assembly and an antenna plane. The pitch assembly is installed above the azimuth assembly; the folding assembly is connected above the pitch assembly; and the front end of the azimuth assembly is connected with the polarization assembly. The antenna plane is formed by a middle antenna plane and the side-surface antenna plane. The folding assembly consists of a torque motor, a lower antenna rotating element and a small bearing II; the torque motor is installed above a torque motor fixed seat including a mounting plane I and a mounting plane II; and the lower antenna rotating element is formed by a mounting plane III, a mounting plane IV, and a mounting plane V. Compared with the prior art, the terminal has the following beneficial effects: the structure is compact; the wind-loading capability is high; the performance is stable and reliable; the antenna plane employs a torque motor transmission way to realize an automat unfolding and folding effect; and a repeated mounting and dismounting link is eliminated.

Description

technical field [0001] The invention is a novel disassembly-free portable satellite communication antenna terminal, which belongs to the field of satellite communication antenna equipment. Background technique [0002] Satellite communication plays an irreplaceable role in emergency communication, but traditional satellite communication: the earth station has a diameter of 1.2-3 meters, weighs several tons, is difficult to carry, and is complicated to operate. Generally, the vehicle-mounted satellite communication system is relatively large in size, weighing more than 50 kilograms, and cannot be carried by individuals, which greatly limits its application occasions. Ordinary portable satellite communication systems, either do not have a driving mechanism, need to manually search for satellites, take a long time to prepare, and the meaning of emergency communication is greatly reduced; or the structure is complex and heavy, and the gap between forward and reverse rotation is ...

[0002] Satellite communication plays an irreplaceable role in emergency communication, but traditional satellite communication: the earth station has a diameter of 1.2-3 meters, weighs several tons, is difficult to carry, and is complicated to operate

Generally, the vehicle-mounted satellite communication system is relatively large in size, weighing more than 50 kilograms, and cannot be carried by individuals, which greatly limits its application occasions

Ordinary portable satellite communication systems, either do not have a driving mechanism, need to manually search for satellites, take a long time to prepare, and the meaning of emergency communication is greatly reduced; or the structure is complex and heavy, and the gap between forward and reverse rotation is large, resulting in weak wind resistance and poor stability and reliability. ; or the antenna surface needs to be disassembled, the antenna surface is assembled during work, and the antenna surface is disassembled at the end, the operation is cumbersome and takes a long time
