<p>The present invention relates to a device for eliminating the perturbation signals received by a reference GNSS station. The device comprises means for receiving a signal of interest emitted by a satellite, including a main antenna with radiation pattern with substantially omnidirectional aperture. It also comprises means for receiving the perturbation signals, said means including a secondary antenna with directional radiation pattern with low elevations and means for receiving said perturbation signals isolated from the signal of interest. It also comprises means for subtracting the perturbation signals from the signal of interest, said means include a means for estimating the differential function for transfer W between the reception pathway of the signal of interest and the reception pathway of the perturbation signals, in such a way as to achieve a coherent subtraction of said signals. Application: GNSS systems with enhanced precision.</p> |
