FIELD: physics.
SUBSTANCE: navigation system is configured to receive signals from a plurality of transmitters (T1-T5, N), having computation means for each transmitter (T1-T5, N) for gathering unprocessed navigation measurements and means of generating a navigation solution. The navigation system has means of checking consistency of the set of unprocessed navigation measurements calculated for the transmitter (N). The transmitter is marked as suitable if its set of unprocessed navigation measurements is considered consistent for use when generating a navigation solution and the transmitter is marked as unsuitable until consistency of the set of unprocessed navigation measurements is confirmed. The navigation system is configured to carry out for an initially suitable transmitter (T1) a preliminary step of acknowledging unsuitability of said transmitter in order to exclude it from generating the navigation solution and in order to allow its reuse in generating the navigation solution.
EFFECT: improved checking of integrity, avoiding use of erroneous unprocessed measurements associated with multibeam uneven propagation of signals.
