GPS POSITIONING DEVICE AND METHOD FOR UNMANED AERIAL VEHICLE BY USING A PLURALITY OF GLOBAL POSITIONING SYSTEM RECEIVERS

摘要

The present invention relates to an unmanned aerial vehicle positioning device and a method using a plurality of GPS receivers installed in an unmanned aerial vehicle. According to various embodiments, the positioning method of an unmanned aerial vehicle provided with a radial GPS fixing stand including three supports of the same length at an angle of 120 degrees from each other comprises: a step of determining whether a plurality of GPS receivers installed on the fixing stand receives a radio wave output from at least one satellite; a step of measuring a time of arrival to the plurality of GPS receivers for the radio wave output from the at least satellite; a step of calculating a distance between the at least one satellite and the plurality of GPS receivers by using the measured arrival time; and a step of determining a moving speed and a current position of the unmanned aerial vehicle by using the calculated distance and an initial position of the unmanned aerial vehicle. According to the present invention, the position can be measured more accurately.
