Abstract
A navigation method using a plurality of pseudo-measurements obtained from satellite signals, the method implementing a Kalman filter bank having a main filter calculating a main navigation solution from the pseudo-measurements originating from satellites, and sub-filters each calculating a secondary navigation solution, and at least one innovation of the pseudo-measurements for each non-excluded satellite and a cross-innovation. An indicator is determined from the sensitivity of the cross-innovation to the innovations of the non-excluded pseudo-measurements. A corresponding navigation system and to a vehicle equipped with same are also provided.
