Abstract: front page image
(EN)In the present invention, a mobile station (2) transmits a first radio signal (S1), and a reference station (3) transmits a second radio signal (S2). Fixed stations (4)-(6) extract phase differences (Δφmf1)-(Δφmf3) between a carrier included in the first radio signal (S1) and reference clocks (Cf1)-(Cf3) of the respective fixed stations (4)-(6), respectively. The fixed stations (4)-(6) extract phase differences (Δφsf1)-(Δφsf3) between a carrier included in the second radio signal (S2) and the reference clocks (Cf1)-(Cf3) of the respective fixed stations (4)-(6), respectively. A server (7) cancels phase offsets (φf1)-(φf3) of the respective fixed stations (4)-(6) by using information on the phase differences between the mobile station (2) and the fixed stations (4)-(6), respectively, and information on the phase differences between the reference station (3) and the fixed stations (4)-(6), respectively, obtains information on distances between the mobile station (2) and the fixed stations (4)-(6), respectively, and calculates the position of the mobile station (2).
(FR)Selon la présente invention, une station mobile (2) émet un premier signal radio (S1), et une station de référence (3) émet un second signal radio (S2). Des stations fixes (4)-(6) extraient des différences de phase (Δφmf1)-(Δφmf3) entre une porteuse comprise dans le premier signal radio (S1) et des horloges de référence (Cf1)-(Cf3) des stations fixes respectives (4)-(6), respectivement. Les stations fixes (4)-(6) extraient des différences de phase (Δφsf1)-(Δφsf3) entre une porteuse comprise dans le second signal radio (S2) et les horloges de référence (Cf1)-(Cf3) des stations fixes respectives (4)-(6), respectivement. Un serveur (7) annule des décalages de phase (φf1)-(φf3) des stations fixes respectives (4)- (6) au moyen des informations sur les différences de phase entre la station mobile (2) et les stations fixes (4)-(6), respectivement, et des informations sur les différences de phase entre la station de référence (3) et les stations fixes (4)-(6), respectivement, obtient des informations sur les distances entre la station mobile (2) et les stations fixes (4)-(6), respectivement, et calcule la position de la station mobile (2).
(JA)移動局(2)は第1の無線信号(S1)を送信し、基準局(3)は第2の無線信号(S2)を送信する。各固定局(4)~(6)は、第1の無線信号(S1)に含まれるキャリアと各固定局(4)~(6)の基準クロック(Cf1)~(Cf3)との位相差(Δφmf1)~(Δφmf3)を抽出する。各固定局(4)~(6)は、第2の無線信号(S2)に含まれるキャリアと各固定局(4)~(6)の基準クロック(Cf1)~(Cf3)との位相差(Δφsf1)~(Δφsf3)を抽出する。サーバ(7)は、移動局(2)と各固定局(4)~(6)との間の位相差情報と、基準局(3)と各固定局(4)~(6)との間の位相差情報とを用いて各固定局(4)~(6)の位相オフセット(φf1)~(φf3)をキャンセルし、各固定局(4)~(6)と移動局(2)との間の距離情報を得て、移動局(2)の位置を算出する。
