Vehicle-mounted satellite communication sky servo and front-end system and method thereof

Abstract

The invention discloses a vehicle-mounted satellite communication sky servo and front-end system, which comprises an antenna system, a servo system and a communication front-end system, wherein, the antenna system comprises an antenna array (1), an antenna mounting reflecting plate (2), an electric bridge (3) and a power divider (4); the servo system comprises an orientation transmission mechanism, a pitching transmission mechanism, a servo controller and a navigation system; the communication front-end system comprises a power amplifier, a low-noise amplifier, a filter and a frequency converter; and the communication front-end system is connected with the communications terminal through a slip ring. The vehicle-mounted satellite communication sky servo and front-end system provided by the invention has the advantages of short catching time, high tracking and response speed, high tracking accuracy, independent tracking and communication, convenience in use, simple structure, good stability and low system cost, and dispenses with catching again in case of false tracking; and the eight-unit forming array antenna is adopted, so the antenna field gain is greatly improved and the communication quality is improved too.

Description

Technical field [0001] The invention relates to a vehicle-mounted satellite communication antenna and front-end system and a method thereof. Background technique [0002] At present, satellite communication technology has been widely promoted and applied in many fields, and the research of satellite communication technology has also become an important topic of communication technology research today. As everyone knows, the fixed satellite antenna communication system on the ground only needs to adjust the antenna to align the satellite, and it can carry out satellite communication conveniently. However, on moving cars, ships and other carriers, due to the bumps of the road, the steering of the antenna carrier, etc. The reason is that the antenna cannot be accurately aligned with the satellite and cannot receive satellite signals in a timely and accurate manner. In order to solve the problem of "stable communication in motion", the technology of "communication in motion" came int...
