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 servo and front-end system and a method for using the same. 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 become an important topic of communication technology research. As we all know, the fixed satellite antenna communication system on the ground only needs to adjust the antenna to align with the satellite, and then the satellite communication can be carried out conveniently. The reason is that the antenna cannot be accurately aligned with the satellite and cannot receive satellite signals in a timely and accurate manner. The track pointing control. [0003] The existing "communication in motion" tracking pointing parties are mainly divided into two methods: active tracking and passive tracking, or a combination of the two. Active tr...
