    Analysis of the earth's surface influence on the accuracy of non directional beacon in mountain terrain
    (University of Zilina, 2021) Novák, Andrej; Novák Sedláčková, Alena; Lusiak, Tomasz; Stelmach, Anna
    This paper deals with the measuring and checking of the Non Directional Beacon using flying laboratory AeroLab 1 at University of Zilina. It is based on the most simple radio navigation concept: a ground-based radio transmitter (the NDB) sends an omnidirectional signal that an aircraft loop antenna receives. Our practical measurement shows that the NDB satisfies ICAO standards and can be used in industrial part of urban area and is functional in spite of the interference. The paper concentrates on the measuring of the Non Directional Beacon (NDB) which is installed close to industrial part of the city. The ADF/NDB navigation system is one of the oldest air navigation system still in use today. One of the paper's goals is to familiarize the aviation public with the practical measurement of this urban area phenomenon in terms of flight safety, which is common in mountainous nations such as Slovakia. The article's other purpose is to educate professionals in the area about this occurrence in terms of its nature as a physical rule, in order to develop solutions to improve the navigation system's measurement accuracy.

    ANALÝZA RUŠENIA SIGNÁLU GNSS NA LETISKU POPRAD- TATRY
    (Žilinská univerzita v Žiline, 2020) Novák, Andrej; Novák Sedláčková, Alena; Stelmach, Anna
    The paper is focused on the GNSS signal interference during the airport approach procedures at small Slovak regional airport Poprad-Tatry. The paper analyzes the simulation of the situation during the identification and monitoring of GNSS signal interference by ground station situated at the airport. Nowadays is still important to develop air transport and increasing the safety and continuity of provided services even at small regional airports. One of the most appropriate possibilities is to use at this kind of airports with insufficiently equipped navigation infrastructure the GNSS approach. The monitoring of reliability of this system and implementation of monitoring the GNSS signal interference in the final phase of the instrument approach will increase the safety of the flight.
