Problems solved by technology

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

Abstract

The invention relates to an antenna structure system based on a 3-UPU two-to-one parallel mechanism. The system comprises an antenna reflector and an antenna holder. The antenna holder drives three liner drivers through three servo motors. Two ends of every linear driver are hinged to upper and lower platforms through universal joints; the upper and lower platforms are both equilateral triangles at same positions; rotation axes of two universal joints of a three-branch connection prismatic pair are mutually orthogonal and connected to vertexes of two triangles respectively; rotation axes of the three universal joints connected with the lower platform are coplanar and concurrent; rotation axes of the three universal joints connected with the upper platform are concurrent but non-coplanar; the 3-UPU two-to-one parallel mechanism antenna structure system is formed. The system allows 'crossing-top' continuous tracking for an antenna, an operation spatial direction of arrival is 0 degrees to 360 degrees, and continuous tracking with any attitudes at a pitching angle of less than + / -90 degrees (the pitching angle is 0 degree when the antenna faces up) is achieved.

Description

Technical field [0001] The invention relates to an antenna structure system based on a 3-UPU two-turn-one-shift 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 continuous tracking of satellite launch vehicles and other aircraft without overhead "blind spots", and satisfactorily solve the problem that the antenna is in its working airspace, that is, pitch: <±90°, Azim...
