ESTIMATING POSITION SYSTEM OF AUTONOMOUS VEHICLE USING CDGPS, AUTONOMOUS VEHICLE HAVING THE SAME AND ESTIMATING POSITION METHOD OF AUTONOMOUS VEHICLE

摘要

PURPOSE: A position estimating system of an autonomous vehicle using a CDGPS(Carrier-phase Differential GPS), and an autonomous vehicle comprising the same and a position estimating method of the same are provided to collect position information of the autonomous vehicle during delay time or cut-out time. CONSTITUTION: A carrier phase correction GPS(Global Positioning System) part(110) is formed to grasp current position through communication with a base station. A GPS part(120) is formed to grasp the current position by receiving a signal from a GPS satellite. A reception conversion part(130) monitors a first signal outputted from the CDGPS part, and is converted to receive a second signal outputted from the GPS part when the first signal is cut out. A position estimation part estimates the current position of an autonomous vehicle on the basis of the first signal or the second signal.
