Beschreibung
Zusammenfassung:	The present invention provides a position estimation system capable of being used in indoors and outdoors for a long time, and a method thereof. The position estimation method of a position estimation system according to the present invention comprises the following steps of: receiving tag signal information from a plurality of gateways, wherein the tag signal information includes an intensity and time information of a signal output from a tag device; generating a fingerprint map by using the tag signal information; and estimating a position of the tag device from the fingerprint map. 본 발명에 따른 위치 추정 시스템의 위치 추정 방법은, 복수의 게이트웨이들로부터 태그 신호 정보를 수신하고, 상기 태그 신호 정보는 태그 장치로부터 출력된 신호의 세기 및 시간 정보를 포함하는 단계, 상기 태그 신호 정보를 이용하여 핑거프린트 맵을 생성하는 단계, 및 상기 핑거프린트 맵으로부터 태그 장치의 위치를 추정하는 단계를 포함할 수 있다.
