Abstract

L’invention concerne un procédé de localisation d’un équipement utilisateur, situé à une altitude donnée, recevant une pluralité de faisceaux radiofréquences émis respectivement par au moins une antenne d’une première station de base, située à une première hauteur donnée, configurée pour émettre selon au moins une première et une deuxième direction de propagation, et par une antenne d’au moins une deuxième station de base , située à une deuxième hauteur donnée, configurée pour émettre selon au moins une troisième et une quatrième direction de propagation. Ledit procédé met en œuvre :- une obtention (40) d’une puissance mesurée par ledit équipement utilisateur pour des faisceaux radiofréquences émis par la première station de base au moins selon la première et la deuxième direction de propagation et des faisceaux radiofréquences émis par la deuxième station de base selon au moins la troisième et la quatrième direction de propagation, délivrant respectivement un premier jeu de puissances mesurées pour la première station de base et un deuxième jeu de puissances mesurées pour la deuxième station de base;- un calcul (41) d’au moins une information par station de base, représentative d’un rapport ou d’une différence entre une première et une deuxième puissances de chaque jeu de puissances mesurées, dite première information de puissance relative pour la première station de base et deuxième information de puissance relative pour la deuxième station de base, - une détermination (42) d’au moins un premier angle représentatif d’une latitude dudit équipement utilisateur dans un repère de l’antenne de la première station de base et un deuxième angle de latitude dudit équipement utilisateur dans un repère de l’antenne de la deuxième station de base, à partir, d’une part, de ladite au moins une première et deuxième informations de puissance relative et, d’autre part, pour chaque information de puissance relative et pour chaque faisceau radiofréquences associé à ladite information de puissance relative, d’un modèle de diagramme de rayonnement d’antenne ; et- une détermination (43) d’une position géographique de l’équipement utilisateur dans un repère de la première station de base au moins à partir des deux angles représentatifs d’une latitude déterminés, de l’altitude de l’équipement utilisateur et des première et deuxième hauteurs données. FIGURE 4The invention relates to a method for locating user equipment, located at a given altitude, receiving a plurality of radio frequency beams respectively emitted by at least one antenna of a first base station, located at a first given height, configured to transmit in at least a first and a second direction of propagation, and by an antenna of at least a second base station, located at a second given height, configured to transmit in at least a third and a fourth direction of propagation. Said method implements: - obtaining (40) a power measured by said user equipment for radio frequency beams emitted by the first base station at least in the first and second directions of propagation and radio frequency beams emitted by the second base station according to at least the third and the fourth direction of propagation, respectively delivering a first set of powers measured for the first base station and a second set of powers measured for the second base station; - a calculation (41) at least one piece of information per base station, representative of a ratio or a difference between a first and a second power of each set of measured powers, called first relative power information for the first base station and second piece of information of relative power for the second base station, - a determination (42) of at least a first angle representative of a latitude of said user equipment in a reference point of the antenna of the first base station and a second angle of latitude of said user equipment in a reference of the antenna of the second base station, from, on the one hand, said at least one first and second relative power information and, on the other hand, for each relative power information and for each radio frequency beam associated with said relative power information, an antenna radiation pattern model; and- a determination (43) of a geographical position of the user equipment in a reference of the first base station at least from the two angles representative of a determined latitude, of the altitude of the user equipment and of the first and second given heights.
