THREE-DIMENSIONAL POSITIONING APPARATUS AND METHOD Russian patent published in 2014 - IPC G01S19/00 

FIELD: radio engineering, communication.

SUBSTANCE: three-dimensional positioning apparatus (10) with a secondary radar base station (12), designed to measure range to repeaters (14) and has at least one radar antenna (16), has a GNSS receiver (18), designed to measure GNSS signals and has a GNSS receiving antenna (20), an inertial measuring unit (22), designed to determine the position of the GNSS receiving antenna, as well as at least one radar antenna in a common coordinate system relative a zero point, and an integrating processor (24, 30, 31), to which are transmitted psedorange measurements of the GNSS receiver, radar range measurements, and movements of the apparatus relative the axis of the common coordinate system measured by the inertial measuring unit (22), and which determines the three-dimensional position of the common reference point by combining the measurements and data, and arm compensation is carried out based on the measured movements.

EFFECT: high accuracy of positioning.
