Statistical computer modeling is implemented to analyze an autonomous system for navigation data integrity monitoring of satellite radio navigation systems using the measurement residual summation method in a sliding window. The analysis is made for integrated optimal information processing algorithms obtained by the methods of the optimal estimation Markov theory. Algorithms are generated for the vertical channel of the navigation complex, which includes an inertial navigation system, signal reception equipment from satellite radio navigation systems, and a barometric altimeter. The possibility of detecting unreliable data in using different measurement residuals, as well as depending on the size of the sliding window, is investigated in the modeling process.
