| description | There is disclosed a computer implemented method for processing the signal emitted by a distress beacon, the signal being received by several satellites and forwarded to at least one ground station, the method comprising the steps consisting in determining a set of hypothetical positions of the beacon, and for at least one of the hypothetical positions, for each satellite, offsetting the signal received and forwarded as a function of the hypothetical position; summing the offset signals; and evaluating the validity of the sum of the offset signals as a function of the presence of a predefined characteristic in the sum. Developments describe aspects such as the temporal and/or frequency offsetting, the construction of a digital replica of the signal transmitted by the beacon, and as the minimizing of the weighted residues of the offsets. System aspects are described, including the calibration of an active antenna or an array of antennas. |
