Shipborne communication-in-motion satellite antenna

Abstract

The invention relates to a shipborne communication-in-motion satellite antenna. The shipborne communication-in-motion satellite antenna comprises an antenna surface, an orientation transmission apparatus, a rolling transmission apparatus, a pitching transmission apparatus and a polarization transmission apparatus. The satellite antenna adopts a brand-new three-shaft stabilization four-shaft tracking structure; the transmission apparatuses of the satellite antenna all adopt gear engagement forms in transmission, so that high stability and precision are achieved, and satellite tracking stability under extreme swing of the shipborne communication-in-motion antenna is improved; a U-shaped rolling wall in the rolling transmission apparatus adopts an aluminum alloy square tube, and the square tube is subjected to cold bending machining by a die, and stress is removed from the shaped U-shaped rolling wall so as to ensure the stability while lowering the cost; a bracket, an orientation rotary platform, a polarized mounting plate, a rolling front side plate and a rolling motor mounting plate adopt sheet metal components, so that the manufacturing cost can be greatly lowered; and in addition, the shipborne communication-in-motion satellite antenna is simple in structure, low in cost, high in stability and economic value, and capable of promoting common popularization and use.

Description

technical field [0001] The invention belongs to the technical field of mobile communication satellite antennas, and in particular relates to a ship-borne mobile communication satellite antenna. Background technique [0002] For fishermen living at sea, the vast sea is a desert of cultural life. Fishermen need long-term fishing operations in the open sea throughout the year, so that fishermen can keep abreast of the country's current affairs news, industry and market information, weather and wave forecasts and other information when they go to sea, which is very important to meet the spiritual and cultural needs of fishermen and harmony The construction of fishing areas plays a very important role, and it is also a vital part of the construction of people's livelihood in our country. [0003] Since only satellite signals can cover at sea, and receiving satellite signals must require the antenna to automatically and accurately track satellites, the current single-action and m...
