Problems solved by technology

[0005] The traditional classic remote sensing and telemetry low-orbit satellite antenna design generally adopts the elevation-azimuth (EL-AZ type) antenna seat, which has an overhead "blind cone area", and the elevation-azimuth antenna cannot be placed in the satellite's overhead "blind cone area". Continuously track satellites in the airspace to realize the demand for uninterrupted and continuous signal work

Abstract

The invention relates to an antenna structure system of a parallel mechanism, which is composed of an antenna reflector joined with an antenna bracket, wherein, the antenna bracket comprises six servo motors that respectively drive six rectilinear telescopic actuating devices; the upper ends of the six rectilinear telescopic actuating devices are articulated with an upper mounting plate and the lower ends are articulated with a lower mounting plate, thus forming a hexapodous parallel mechanism. The parallel mechanism can satisfactorily solve the problem of obtaining remote sensing and telemetry signals and data of satellites and carrier rockets, realize antenna 'passing zenith' and continuous tracking in airspace and achieve a hemisphere working airspace.

Description

technical field [0001] The invention relates to an antenna structure system based on a parallel mechanism. Antenna structure system for aerospace remote sensing, satellite "three remote" technology (remote sensing, telemetry, remote control technology) and satellite communication. The antenna structure system, the servo control system, and the feeder and feeder system (referred to as: sky, servo, and feed) form an antenna system to realize remote sensing, telemetry, and remote control information acquisition and instructions, and to realize satellite communication information transmission and processing. In particular, it can obtain telemetry signals and data in the effective airspace of satellites, launch vehicles and other aircraft, realize a continuous tracking antenna system without overhead "blind spots", and satisfactorily solve the continuous tracking of any attitude in the airspace of the antenna hemisphere. The technical solution of the invention belongs to the techn...
