초록

This study was carried out to develop turning radius measuring method and device of using a DGPS speed sensor for agricultural tractors. The measurement system consisted of a DGPS speed sensor, a data acquisition device, a touch panel, a photo sensor, a radio modem and a notebook computer. Three methods were developed: average of turning speed-time method, integral of turning speed-time method, and speed-heading angular velocity method. Best method was average of turning speed-time method which could be used with a maximum error 2.7 cm.
