Popis: The paper presents a method for monitoring the integrity of telemetric data on the state of a mobile object, namely, an aircraft engine, based on a comparison of technological time series. The technological time series obtained from the mobile object are compared with the technological time series generated by the model of the mobile object at the developer (manufacturer). Comparison of time series is carried out in the selected time window by calculating the consistency parameters: the coefficient of determination, Euclidean distance and the average percentage of deviations. According to the calculated consistency parameters, the type of consistency in a given time window (7 types) is determined, and the type of dynamics of the mobile object is also determined: static or dynamic. The decision on data integrity is made according to the formulated rules of fuzzy logic, which are based on three parameters: the type of dynamics of the mobile object, the type of consistency of technological time series and the signal of the control system. Testing of the proposed method was carried out on the data generated by the automatic control system of the aircraft engine. The estimate of the probability of the correctness of the decision made was 0.85.
