“…K-a posteriori dispersion of the filtration errors of the status vector. Equations (14) and (15) determine the structure, accuracy, and resistance to wide-band band interference of DME, which has the best (depending on the simplifications adopted in deriving relations (14) and 15the accuracy characteristics. Based on the derived algorithms (14) and 15, we simulated the measurement of navigation parameters by the DME system.…”

“…The ability of the DME receiver to operate under wide-band fluctuation conditions was verified through modeling. By calculating the relation (15) and substituting the covariance matrix of the a posteriori error filtering of the signal parameters (3) K(t) into Equation 14, it is possible to model the process of measuring the distance of the flying object from DME using a PC modeling, thus allowing the dependence of DME characteristics on the change of input signal parameters, wide-band fluctuation failure, and flight dynamics of the flying object to be determined. Modeling results can be used in the practical construction of the DME receiver [4,21,22].…”

“…The DME system has some drawbacks-including low resistance to interference [4][5][6][7][8][9][10][11][12][13][14][15]. Therefore, it is of practical importance that the task of optimizing the receiver of a DME system that operates under wide-band fluctuation interference conditions be addressed.…”

“…Several analyses performed on radio navigation systems [4][5][6][7][8][9][10][11][12][13][14][15] conclude that they operate under conditions of interference. The most typical forms of interference affecting its operation are termed as the wide-band fluctuation interference, narrow-band interference, and chaotic pulse interference.…”

Accurate navigation systems allow us to optimize the trajectory of flying objects and thus solve environmental problems in aviation and their impact on public health. In this paper, we present one of the methods of assessment of accuracy and resistance to interference of distance-measuring equipment (DME). By using computer technology, the method enables us to determine the potential but also the real error measuring the distance of the flying object from DME. The credibility of the respective results of the solution on the task of DME optimal rangefinder synthesis depends on the accuracy of the previous data used, i.e., mathematical models of the respective flying objects flight dynamics, useful signals, and their parameters and interference. DME systems have an impact on air transport safety, and therefore the impact of interference on their operation must be investigated.
