POSITIONING METHOD OF RADIO COMMUNICATION DEVICE USING SELECTIVE FUSION |
摘要 |
PROBLEM TO BE SOLVED: To provide a method of highly accurately finding the position of a radio communication device. SOLUTION: In an estimated location calculating method, a signal is first received from a fixed radio transmitter and a plurality of temporary estimated locations are calculated by using a plurality of calculation methods of triangulation, k-most proximity neighborhood and minimum polygon. Based upon the calculated temporary estimated locations and reference information relating to radio communication environments, high-accuracy estimated location is calculated.
