SELF-CALIBRATION METHOD FOR GPS SIGNAL BEAMFORMING AND APPARATUS THEREOF

摘要

The present invention relates to a GPS signal beamforming technique and, more specifically, to a method and device for beamforming after self-calibration by using only a GPS satellite signal outdoors without an additional calibration device. In order to achieve the task shown above, the present invention provides a self-calibration method for GPS signal beamforming to conveniently perform the beamforming technique without the installation and operation of the additional calibration device. According to the present invention, a weak satellite signal can be precisely measured by measuring the magnitude and phase with a tracking channel of a GPS receiver for self-calibration and differentiating and filtering the same.;COPYRIGHT KIPO 2014
