Abstract

Des variations de l'indicateur d'intensité de signal reçu mesurées dans une station mobile peuvent provoquer des variations de la position de la station mobile qui est détectée à l'aide de l'indicateur d'intensité de signal reçu. Ce dispositif de détermination de position peut être équipé d'une unité d'acquisition d'informations d'intensité qui acquiert des informations d'intensité indiquant l'indicateur d'intensité de signal reçu dans une station mobile pour chacune d'une pluralité de stations de base installées en chacune d'une pluralité de positions prédéterminées. Le dispositif de détermination de position peut être équipé d'une première unité d'identification qui identifie, parmi la pluralité de stations de base, une première station de base ayant l'indicateur d'intensité de signal reçu le plus élevé dans la station mobile sur la base des informations d'intensité. Le dispositif de détermination de position peut être équipé d'une seconde unité d'identification qui identifie, parmi la pluralité de stations de base, une seconde station de base ayant le second indicateur d'intensité de signal reçu le plus élevé dans la station mobile sur la base des informations d'intensité. Le dispositif de détermination de position peut être équipé d'une unité de détermination qui détermine la position de la station mobile sur la base d'une première position indiquant la position de la première station de base, d'une seconde position indiquant la position de la seconde station de base, et d'un premier indicateur d'intensité de signal reçu dans la station mobile pour la première station de base.
