Satellite communication system for meteorological prediction

Abstract

The invention discloses a satellite communication system for meteorological prediction. The system comprises a base and a supporting column fixedly arranged on the base, a satellite pot is fixedly arranged at the upper end of the supporting column, a rotating shaft is rotationally arranged in the satellite pot, a water leakage mechanism is further arranged on the bottom wall of the satellite pot, and a telescopic rod is rotationally arranged on the rotating shaft. A receiver is fixedly arranged on the telescopic rod, and water tanks are arranged on the side walls of the two sides of the supporting column in a sliding mode; a communicating pipe is arranged between the bottom walls of the two water tanks in a communicating manner; the communicating pipe penetrates through the supporting column, and water drainage mechanisms are further arranged on the bottom walls of the two water tanks. Sliding blocks are fixedly arranged on the side walls of the sides, close to the supporting columns, of the two water tanks. According to the invention, sound and vibration generated by continuous collision between falling rainwater and the satellite pot are effectively weakened or even eliminated, and the influence of the sound and vibration on a wireless channel received by a receiver is avoided.

Description

technical field [0001] The invention relates to the technical field of satellite communication systems, in particular to a satellite communication system for meteorological prediction. Background technique [0002] The satellite communication system is actually a kind of microwave communication. It uses satellites as relay stations to transmit microwave signals and communicate between multiple ground stations. The main purpose of satellite communication is to achieve "seamless" coverage of the ground. The satellite communication system consists of communication Composed of satellites and earth stations. The earth station can only point to a certain geostationary satellite, and two or more earth stations can establish a direct satellite circuit through the same geostationary satellite. Such as satellite transmission of TV or radio programs, different transponders on a geostationary satellite can be used to transmit different programs. state predictions; [0003] The existi...

Problems solved by technology

[0003]The existing satellite communication system for weather forecasting will constantly collide with the satellite dish when the rain falls, and the sound and vibration will affect the reception The wireless channel received by the receiver, the higher the frequency of the system, the greater the impact of rain, which is often said to be part of the rain attenuation; at the same time, the surface of the existing receiver is often uneven due to functional requirements. , there will also be a small amount of water stored on the surface of the receiver, which will cause rain attenuation on the surface of the receiver, which further interferes with the signal receiving and transmission process. For this, we propose a satellite communication system for weather forecasting
