HIGH-SENSITIVITY GPS DEVICE WITH DIRECTIONAL ANTENNA

摘要

effective use of a weak GPS signal which exists in a variety of environments allow us to accurately find their place in these circumstances causes the electronic device. The electronic device utilizes an antenna to carry out sequential scanning in multiple directions for the GPS (global positioning system) signal. Electronic device also analyzes the GPS signals obtained from the scanning in multiple directions to determine the number of the acquired GPS satellite that provides a GPS signal. GPS signals include code phase of the GPS satellite acquisition. Then, the electronic device based on the code phase of the acquisition, when the number of the acquired GPS satellite to meet the threshold GPS satellites and calculates the position of the electronic device. ;
