Hybrid inertial system onboard a mobile carrier comprising an inertial measurements unit, at least one platform for integrating inertial data, at least one exterior sensor and a multi-hypothesis hybridization filter, the said system being characterized in that the said hybridization filter implements at least the following steps:

Hybrid inertial system with non-linear behaviour and associated method of hybridization by multi-hypothesis filtering

The invention proposes a method of rejecting interference disturbing the reception by means of a reception system, of a signal emanating from a transmission system, the method comprising a calculation for weighting the signals S(t), i varying from 1 to K, emanating from the reception system, based on the intercorrelation matrix Rfor the signals S(t), the matrix Rcomprising on its diagonal the autocorrelation terms of the signals S(t). The method is chiefly one wherein the weighting calculation comprises a step consisting in modifying the autocorrelation terms of the diagonal of the matrix R
