    Opis:
    Aim of publication is to introduce reader with general need and current situation of development of air traffic management systems and evaluation of actual operating network of aviation electronic support systems. The theme of the contribution is actual because there is currently an increase in the volume of the air traffic, which places increased demands on the safety level of air transport. Attempting to find new answers related to insufficient navigation systems has led aviation authorities to develop progressive systems based on cooperation with satellite navigation systems. Solution for capacity limited airports is development of system GBAS – Ground Based Augmentation System. The main purpose of publication is to present drafts of possible rationalization of navigation infrastructure of M.R. Stefanik airport. The effort to use the maximum potential of airspace consisted in the search for new concepts and trends in air traffic management based on the development of the technical pillar and new ways of managing the entire ATM system.

    Opis:
    This paper describes various methods of flying object positioning with the emphasis on their accuracy. Based on the accomplished analysis, we will select the most appropriate method to determine the position of a flying object for relative navigation purposes. The primary criterion for choosing a positioning method is the accuracy of distance measurement within users working in the aviation communications network. The results presented in the paper have been based on mathematical modelling and computer simulation performed in the Matlab programming environment. The results obtained can be used to navigate flying or non-flying objects that work in the air communications network.

    Opis:
    In this paper, the issue of teaching professional aviation subjects in the field of higher education air transport was ad‐dressed. We present some research results in the field of didactics of professional aviation subjects, teaching effectiveness, motivation and evaluation of students in education. In this work we present some approaches to the development of didactics of professional subjects in Slovakia. We state that the subject of didactics is the student, teacher and knowledge forming the didactic tri‐angle. Didactics of professional subjects examines the possibilities of transforming the knowledge of technical scientific disciplines into the content of education, didactic systems, teaching projects and the studentʹs knowledge. We researched the area of didactics of professional aviation subjects with a focus on motivating students to study. We managed to involve a large sample of students in the research, which helped us in‐crease the objectivity of the results. Based on the research results, we recommend some measures to increase the quality of higher education of students in the field of air transport. The motivating goal for our research is to support the quality of education at the Faculty of Aeronautics of the Technical University of Košice.

    Opis:
    This article presents an analysis of the Galileo E1 signal and its sensitivity to different types of interference. The research involved modeling white noise, chaotic impulse interference, and narrowband interference and the effects of these interfering signals on the E1 signal. Based on the available information, spectral structures were created for the mentioned types of interference, and subsequently, these interferences were integrated into the E1 signal in the Matlab program environment. A Kallman filter was used to filter out white noise from the additive mixture of the E1 signal and white noise. The research aimed to analyze the influence of white noise, chaotic impulse interference, and narrowband interference on the spectral power density of the E1 signal. The results of this work can be used in the design of robust receivers and signal structures capable of withstanding these types of interference.

    Opis:
    The aim of this paper was to describe the random phase of the E6 signal, the Galileo satellite navigation system. Based on the available information, mathematical models of the measurement signals of the Galileo system were created. The frequencies of individual signals were determined and their structure visualized. A block diagram of the generation of individual signals is also shown. The main contribution of the paper is the creation of a random phase model of the E6 signal from the Galileo system. In accordance with the technical data of the Galileo system, the parameters of the random phase model were determined. The simulation results confirmed that the frequency instability of the continuous signal E6 n received from the satellite is a stationary process. The short-term stability of the frequency ranges from 10-13 to 10-14. The simulation results confirmed that the Doppler effect significantly affects the random phase of the E6 signal. This phenomenon can affect the results of navigation measurements using the E6 signal. The modeling and simulation results of the random phase of the E6 signal presented in the paper can be used to evaluate the immunity of the Galileo navigation system to interference.
