Title (EN) POSITION ESTIMATION SYSTEM
(FR) SYSTÈME D'ESTIMATION DE POSITION
(JA) 位置推定システム
Abstract:
(EN) The present invention estimates the position of a transmission device with sufficient precision. A position estimation system 10 is provided with: a transmission device 20 having a plurality of transmitters 21, 22 disposed symmetrically with respect to a prescribed reference position; a plurality of receivers 31, 32, 33, 34, 35, 36, 37, 38 that receive radio waves transmitted from the plurality of transmitters 21, 22; and an estimation tool 51 that estimates the position of the transmission device 20 on the basis of the reception strength of radio waves received by each receiver 31, 32, 33, 34, 35, 36, 37, 38.
(FR) La présente invention estime la position d'un dispositif de transmission avec une précision suffisante. Un système d'estimation de position (10) est pourvu : d'un dispositif de transmission (20) ayant une pluralité d'émetteurs (21, 22) situés symétriquement par rapport à une position de référence prescrite; d'une pluralité de récepteurs (31, 32, 33, 34, 35, 36, 37, 38) qui reçoivent des ondes radio émises à partir de la pluralité d'émetteurs (21, 22); et d'un outil d'estimation (51) qui estime la position du dispositif de transmission (20) en fonction de l'intensité de réception des ondes radio reçues par chaque récepteur (31, 32, 33, 34, 35, 36, 37, 38).
(JA) 送信装置の位置を十分な精度で推定する。 位置推定システム10は、所定の基準位置に関して対称的に配置された複数の送信機21,22を有する送信装置20と、複数の送信機21,22から送信される電波を受信する複数の受信機31,32,33,34,35,36,37,38と、各受信機31,32,33,34,35,36,37,38が受信する電波の受信強度に基づいて送信装置20の位置を推定する推定ツール51とを備える。
