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

Embodiment Construction

[0023] A preferred embodiment of the present invention is described as follows in conjunction with accompanying drawing:

[0024] exist figure 1 It shows that the antenna system (1) is composed of the antenna structure system (2), the corresponding feed system (3), the servo control system (4) and its corresponding supporting electronic equipment, which realizes automatic tracking of satellites and aircraft, and completes the satellite Or aircraft signal and data transmission, analysis and processing.

[0025] see figure 2 and image 3 , the antenna structure system of the parallel mechanism consists of an antenna reflector (5) and an antenna mount (6).

[0026] see Figure 4 and Figure 5 , the antenna structure system antenna reflector (5) consists of a sub-reflector (feedforward without sub-reflector, only feed-back type has a sub-reflector) and its supporting structure (7), main reflector panel (8), back frame structure (9) and centrosome (10).

Abstract

The invention relates to a parallel mechanism based antenna structural system. The parallel mechanism based antenna structural system comprises an antenna reflector jointed with an antenna mount; the antenna mount is structured in a mode that six straight line telescopic driving apparatuses are respectively driven by six servo motors or hydraulic oil cylinders; the adjacent two upper ends of the six straight line telescopic driving apparatuses are crossed and hinged with the lower surface of a triangular upper platform through a spherical hinge while the adjacent lower ends of the six straight line telescopic driving apparatuses are hinged with the upper surface of a hexagonal lower platform through hooke joints (universal joints); the upper platform and the lower platform are separated at an angle of 60 degrees; six sets of straight line telescopic apparatuses are linked with the upper platform and the lower platform through three spherical hinges and six hooke joints (universal joints) to constitute the 3 / 6-SPU type parallel mechanism based antenna structural system. The 3 / 6-SPU type parallel mechanism based antenna structural system can realize overtop continuous tracing of the antenna, and can reach a pitch of minus 5 degrees to 185 degrees at the position within 0 to 360 degrees (assumed that the angle of pitch of the antenna in the horizontal plane is 0 degree or 180 degrees), so that continuous tracing at any position postures exceeding semispherical working airspace is realized.

Description

Technical field [0001] The invention relates to an antenna structure system based on a 3 / 6-SPU type Stewart 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 working airspace of the antenna's super hemisphere, that is, pitch: -5°~185°, azimuth : Continuous tracking of any pos...
