Ultra-light satellite portable station

Abstract

The invention relates to the technical field of communication satellites, in particular to an ultra-light satellite portable station comprising an antenna assembly and a support frame. The antenna assembly comprises an antenna surface, feed supports, a pitch transmission mechanism and an azimuth transmission mechanism. An electric box is integrally arranged on the back surface of the antenna surface. The feed supports are located on the two sides of the antenna surface. The feed supports are connected with the pitch transmission mechanism. The pitch transmission mechanism is connected with theazimuth transmission mechanism. The azimuth transmission mechanism is connected with the support frame through a quick mounting mechanism. The front surface of the antenna surface is connected with asecondary reflection surface at a fixed included angle through a radio frequency transceiver assembly limiting pull rod and a radio frequency transceiver assembly. An antenna controller, a satellitemodem and built-in equipment and the like are placed on the back of the antenna surface, which avoids direct sun exposure and optimizes the weight of the antenna. The antenna surface uses the folded hinge design, which eliminates the traditional multi-lobe assembly, greatly saves the erection time and enhances the integrity of the antenna.

Description

technical field [0001] The invention relates to the technical field of communication satellites, in particular to an ultra-light satellite portable station. Background technique [0002] In existing applications, the bias-fed satellite antenna generally adopts a box structure, such as figure 1 As shown: the whole antenna generally consists of antenna surface 1-1, feed source bracket 1-2, feed source system, azimuth and pitch transmission parts 1-4, electrical box 1-3, windproof bracket 1-6, handle 1-5, etc. Composed of components, the electrical box and the azimuth and pitch transmission parts are installed on the bottom plate of the antenna structure, and the antenna feeder system is installed on the azimuth and pitch transmission parts of the antenna. This kind of antenna structure meets normal communication needs, and has the advantages of compact volume after storage, large volume of electrical box, and multiple communication machines built in. But there are certain di...

AI Technical Summary

Problems solved by technology

[0003] 1. The electrical box is at the bottom of the antenna, so it does not have the ability to ford;

[0004] 2. The feed bracket part contains power amplifiers, radio frequency and other equipment that are heavy, but there is no corresponding counterweight on the back of the antenna surface, so the center of the pitch rotation part is offset from the front end, and a larger reducer and motor are required for pitch rotation;

[0005] 3. The antenna electrical box is located at the front end of the antenna, and it is easily exposed to direct sunlight when the temperature is high in summer, causing the temperature inside the box to rise abnormally, resulting in failure of communication equipment;

[0006] 4. The antenna surface is as
