Title:
HIGH-PRECISION CALIBRATION POSITIONING APPARATUS FOR RADAR SATELLITES AND GNSS SATELLITES
Document Type and Number:
WIPO Patent Application WO/2021/244495
Kind Code:
A1
Abstract:
A high-precision calibration positioning apparatus for radar satellites and GNSS satellites. The apparatus comprises: a bottom plate (9); a base (8) detachably fixed onto the bottom plate (9); a mounting platform (5) detachably fixed onto the base (8) and capable of horizontal rotation, the tangents between a first side surface and second side surface of the mounting platform (5) and the horizontal plane respectively being consistent with the flight directions (10, 11) of an elevator orbit radar satellite and the included angles thereof with the horizontal plane respectively being adapted to the local angle of incidence of the elevator orbit radar satellite; a dihedral angle reflector detachably fixed onto the first side surface and/or the second side surface of the mounting platform (5) to be parallel to the flight directions (10, 11) of the elevator orbit radar satellite and adapted to the local angle of incidence of elevator orbit radar signals; and a GNSS antenna connector (7) arranged on the top part of the mounting platform (5). By means of replacing mounting tables (5) of different inclinations and included angles and reflecting panels (1, 2, 3, 4) of different shapes and sizes, the present apparatus achieves the RCS theoretical maximum value of dihedral right angle reflection of the radar satellite signals, and synchronously implements GNSS high-precision positioning by means of the GNSS antenna on the top part.
