Title:
POSITIONING DEVICE AND POSITIONING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/045100
Kind Code:
A1
Abstract:
The present disclosure relates to a positioning device and a positioning method which can achieve location positioning with high accuracy at a low working cost by using a small, lightweight, and comparatively low-priced GPS antenna and an IMU. According to the present invention, an incident angle of a carrier wave to the GPS antenna is detected in the global coordinates, the orientation of the GPS antenna is detected in the global coordinates by the IMU, the incident angle of the carrier wave to the GPS antenna in the global coordinates is converted, on the basis of the orientation, to that in the local coordinates by means of a rotation matrix corresponding to the orientation, a phase difference due to a corresponding PCV is obtained by specifying an azimuthal angle and an elevation angle on the basis of the incident angle in the local coordinates, and a PCV correction value is obtained from the phase difference. The phase of the carrier wave is corrected by means of the calculated PCV correction value, and the location positioning is performed. The present disclosure can be applied to a positioning device.
