摘要

The problem of information failures (IF) identification in not redundant dead-reckoning navigation system (NS) is considered at passage by terrain object of reference points (RP). At RP the geodetic parameters accessible to measurement and in NS are beforehand measured. Thus the stop of object in RP, fixing of the moments of passage by object RP by means of special gauges is not supposed. For traditionally used models of NS IF, RP, the way of formation of a surplus information is considered without detection of the moment of passage by object RP. The problem of IF identification with attraction of RP data is formulated within the framework of the theory optimal parameter estimation at multialternative model of a signal. The restrictions determining novelty of the suggested approach are proved, allowing to lower computing expenses and to receive algorithms of identification IF comprehensible to practical realization in real time.
