Determining the position of aircraft using satellite navigation systems (SNS) is becoming increasingly challenging due to the widespread use of jamming devices that interfere with, suppress, or distort satellite signals. The lack of position information can lead to serious consequences and even catastrophes. Emerging autonomous navigation methods require accurate flight data to correctly determine the true location of the aircraft. This paper examines methods for correcting barometric altitude within such software and hardware systems. Objective – to develop a method for correcting barometric altitude readings for a software-hardware complex of an autonomous navigation system.

A method has been developed that reduces the statistical error component in barometric altimeter readings to deviations from the true flight altitude not exceeding 4 m. The proposed barometric altitude correction method allows the software system to operate with real flight data obtained using both barometric and radio altimeters.
