摘要
The present invention relates to a method (50) for estimating a direction of a satellite (20) in the transfer phase, said direction of said satellite being estimated with respect to a measurement antenna (30) by executing a plurality of steps (52) of measuring the power of reception, by said measuring antenna, of a target signal emitted by said satellite (20), for different pointing directions of said measuring antenna. In addition, since the target signal comprises a substantially sinusoidal component, referred to as a "single-frequency component", each power measurement step (52) comprises a frequency-domain transposition of a digital signal obtained from a signal provided. by the measuring antenna (30), so as to obtain a frequency spectrum of said digital signal over a predetermined frequency band comprising said single-frequency component, and the power measurement for the pointing direction considered is determined from a maximum value of the frequency spectrum.
