Observation Trajectory Model for Radio-Frequency Aviation Landing Systems

The aim of the paper is to create software-operational control of the current precision and reliability of onboard angular coordinates measurements by applying optimal discrete filtering methods, provided that they help simplify the technical implementation of the optimal filter by the criterion: accuracy - amount of computing resources. Applying of special methods of signal processing should not reduce the accuracy of measurements under nominal conditions, and when faults appear, it is advisable to use the principle of continuity and enhancement of the functionality of classical signal processing methods.
