Abstract
System for receiving satellite signals jammed by at least one source of interference and by a thermal noise comprising means for receiving the said satellite signals, means for filtering the said satellite signals, in order to remove the disruption from the said sources of interference. The system also comprises first means for determining a first covariance matrix of the satellite signals, adding means for adding respectively a first coefficient to at least one element of the diagonal of the said first covariance matrix in order to obtain a second covariance matrix, second means for determining, on the basis of the said second covariance matrix, second coefficients used by the said filtering means. The system also comprises means for detecting a first power of the said thermal noise, third means for dynamic determination of the value of the said first coefficients, on the basis of the first power.
