Fixed satellite communication earth station | fixed base station antenna

Fixed Antenna

In order to further improve the ability to deal with special disasters and emergencies, the national emergency rescue department has continuously strengthened the construction of emergency rescue equipment. When a sudden occurrence occurs, first of all, ensuring the smooth communication of incidents and communications is a top priority, using satellite security. Field communication is the best choice. The bandwidth of satellite communication is 1M, 2M, 4M, 8M ------, which can transmit the voice, data and image of the accident scene to the command center in real time, which plays an irreplaceable role in the command and decision of the command hall. At the same time, it has greatly improved the efficiency of emergency rescue.
The Fixed Antenna  is composed of a main reflector, a sub-reflector, a feed, a chassis, an azimuth driving mechanism, a pitch driving mechanism, an azimuth sensor, a pitch sensor, an azimuth angle limiter, and a pitch angle limiter. The main reflecting surface of the antenna is a shaped paraboloid, which is stretched with rust-proof alloy aluminum, and the high-strength aluminum alloy profile is used as a back surface of the reflecting surface, so that the antenna has strong wind resistance and sufficient strength to ensure main reflection. Surface profile accuracy. The secondary reflecting surface is an ellipsoidal shape formed by rust-proof alloy aluminum. The main and auxiliary surfaces are all sprayed with high-pressure electrostatically sprayed epoxy polyester plastic layer. The steel parts are coated with hot-dip galvanizing or hot-spraying zinc to enhance the corrosion resistance.
The emergency mobile satellite communication Tianshang system project developed by our company has fully applied the current new technological achievements such as satellite communication technology, single-chip technology, electronic circuit technology, automatic control technology, mechatronics technology and mechanical structure technology, and has been independently designed and developed. It realizes the mobility, portability, high gain, low loss, automatic pointing and tracking, and tracking of designated satellites of the emergency satellite communication earth station antenna system to meet the transmission function of two-way multimedia (audio, video) data. This R&D project has the characteristics of small size, light weight, high bandwidth, fast su star (automatic satellite capture in 55 seconds), and individual operation.
