Abstract
A method for locating a terminal in a coverage area using a telecommunication network, the network including a multi-beam satellite, the area including various cells, each associated with a beam for linking to the satellite to which a frequency band is assigned, the method including: performing the uplink transmission of a message incorporated into a modulated signal to the satellite at a frequency shared by three different uplink beams such that the message is received by the satellite with three different amplitudes; performing the downlink transmission of three modulated signals incorporating the message, the first, second, and third signals each corresponding to a different beam from among the three beams; receiving the first, second, and third signals; determining the amplitudes of the message within the first, second and third signals; and determining the location of the terminal from the amplitudes of the message within the first, second, and third signals.
