Turntable for portable ground satellite station

Abstract

The invention relates to the technical field of satellite communication, and discloses a rotary table for a portable ground satellite station, which comprises an upper cavity, a lower cavity and a driving mechanism, wherein the upper cavity is mounted with the lower cavity through a seal ring in a matched manner; the driving mechanism is arranged in the upper cavity; a motor in the driving mechanism adopts a double-shaft stretched manner; one end of the motor in the driving mechanism is connected with a deceleration device; the other end of the driving mechanism is connected with a manual handle. The rotary table adopts independent modularized design, so as to enhance the suitability and the practicability of the rotary table; the weight of the portable ground satellite station is reduced effectively; the size is reduced; the carrying is convenient; the service life in an harsh environment is prolonged; the functional reliability during use in the harsh environment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a turntable for a portable ground satellite station. Background technique [0002] In order to realize the long-distance and real-time transmission of information, most of the communication links need to be relayed through satellites. Satellite relay refers to the transfer of data between ground equipment through one or more orbiting satellites. Since orbiting satellites are always in motion , in order to realize the communication with the satellite, the ground equipment needs to carry out the star alignment before the communication. Early star-to-satellite equipment used fixed devices, commonly known as fixed stations, which could realize star-to-satellite functions, but were inflexible. Later, mobile star alignment equipment appeared in the development, which can be divided into manual and automatic methods: manual mobile star alignment equipment requires the o...

Problems solved by technology

The turntables in the prior art usually do not have a manual function or the manual mode is very inconvenient. In addition, the motors and reducers selected by different manufacturers are different, and the turntable can only be used with its own shell, and the scalability is poor.

Due to the limitation of the finished equipment, the turntable is often large in size, heavy in weight, not strong in self-locking ability, unreasonable and beautiful in structure and appearance, poor in wind resistance and rain resistance, and its performance and service life are greatly reduced when used in harsh environmental conditions. reduce
