ALTERNATIVE ENGINE SYSTEMS AND THEIR IMPACT ON THE ENVIRONMENT
(Žilinská univerzita v Žiline, 2020) Novák, Andrej; Kováčik, Ľubomír; Lusiak, Tomasz
The article deals with the operational characteristics of alternative aircraft propulsion systems and their impact on the environment. Recently, the issue of alternative aircraft propulsion systems has been brought to the forefront. Particularly with reference to the environment, which in the case of aviation is represented by reducing noise emissions while reducing CO2 emissions. These issues are properly addressed by ICAO in its agenda, defining standards for reducing aviation emissions in Annex 16. The University of Žilina has special laboratories dealing with the environmental impact of aviation and subsequent research aimed at reducing it.
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.
MEASUREMENT OF GNSS INTERFERENCE AT AIRPORT ZILINA
(University of Zilina, 2019) Kováčik, Ľubomír; Novák, Andrej; Lusiak, Tomasz
The paper described the problems of GNSS interference measurement at airport Zilina. The Global navigation satellite systems (GNSS) are widely used both for civilian and military operations to determine the location, speed, acceleration, and trajectory of the user on the ground. GNSS refers to a constellation of satellites that provide signals from space transmitting positioning and timing on data receivers. The intentional errors include jamming and spoofing which are caused by systems sharing the same frequency illegally. The method for measuring signal interference is defined by the parameters that affect the calculation of the position of interest. Monitoring the extent of the interference and its impact is a necessary procedure for the successful management of aircraft operations at the airport.
