Abstract
The aircraft navigation complex consisting of the inertial (ANC) and satellite (SNS) navigation systems is considered. An algorithm for the detection accuracy and stability increasing at the failures of the aircraft navigation complex in the mode of joint operation of the ANS and SNS, as well as in the absence of a signal from the SNS is proposed. In the linear Kalman filter the Chi-square test is used. The results of mathematical modeling have shown the high efficiency of the algorithmic solution. Keywords aircraft; inertial navigation system; satellite navigation system; linear Kalman filter; fault tolerance; Chi-square test
