L'invention concerne un système de détermination de position dans lequel, si un terminal est présent dans une zone de balise configurée par un terminal de balise mais pas dans la plage de précision requise, alors le terminal est déterminé comme n'étant pas présent à l'intérieur de la zone de balise même si le signal de balise peut être reçu. Dans un environnement dans lequel un ou plusieurs terminaux de balise sont installés, ce système de détermination de position estime la position d'un terminal d'utilisateur pouvant recevoir des signaux de balise. Selon un mode de réalisation représentatif, un ou plusieurs terminaux de balise de terminaison sont installés de sorte que tout ou partie de la partie de bordure d'une zone efficace prédéfinie configurée à l'intérieur de la zone de balise du terminal de balise est couverte par des zones de non-détection configurées par les terminaux de balise de terminaison, et même si le terminal d'utilisateur reçoit un signal de balise, si le terminal d'utilisateur est déterminé comme étant à l'intérieur de l'une quelconque des zones de non-détection, ledit terminal d'utilisateur est déterminé comme n'étant pas présent dans la zone de balise.
