Abstract (en)
[origin: WO2021219966A1] The invention relates to a method for geolocating an item of user equipment located at a given altitude, receiving a plurality of radio beams emitted in at least a first and a second propagation direction by at least one antenna of a first base station and by at least one antenna of a second base station, respectively, in at least a third and a fourth propagation direction. Said method involves: • - obtaining (E300) a power measured by said item of terminal equipment for radio beams emitted by the first base station; • - calculating (E310) at least one item of information per base station, representative of a ratio or of a difference between a first and a second power of each set of measured powers; and • - determining (E320) a position of said item of user equipment at the given altitude.
