Accuracy is an important factor in air traffic management which is why high requirements are necessary for each navigation system. The aim of this article is to describe the principles of the RelNav system and telemetry and their accuracy. We present the algorithms of the relative navigation system, which could be used for air traffic control in the case of the unavailability of satellite navigation system signals. This article sums up the different positioning methods, and deals with the accuracy of the relative navigation system (RelNav). Furthermore, the article considers the factors that influence the positioning accuracy. For this task, a computer simulation was created to evaluate the accuracy of the telemetric method. Next, we discuss the principles of telemetry and algorithms for calculating the position of the flying object (FO).

The objective of this paper is to present a comprehensive status of cyber security challenges in ARTAS surveillance data processing system. The cyber security is a major concern of current Air Traffic Systems. It is mandated by European Union as well as national law. Therefore, EUROCONTROL as the provider the ARTAS application conducted a comprehensive security assessment is to identify security vulnerabilities of the systems. For this purpose, a grey-box penetration testing was conducted by EUROCONTROL’s security experts. The numerous findings are currently mitigated by the fact that ARTAS systems should be isolated and restricted in a secure architecture. The next version of ARTAS application is addressing the most critical issues.

“…Tasks of the synthesis and analysis are based on the application of mathematical models of dynamic systems (object of navigation), signals, interference, and information processes [4,[16][17][18][19][20][21][22][23][24][25]. The higher the precision of these a priori data, the higher the credibility of the results of the synthesis and analysis.…”

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.
