Selected Aspects of Using the Telemetry Method in Synthesis of RelNav System for Air Traffic Control

Abstract

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).

Selected Aspects of Navigation System Synthesis for Increased Flight Safety, Protection of Human Lives, and Health

“…As mentioned in the introduction, in our research we used the knowledge we gained when studying the possibility of using the telemetry method to navigate flying objects in the event of failure of satellite navigation systems signals. Substantial results of this research are presented in [5,24]. These works confirm that poor quality satellite systems signals have a significant impact on aviation safety.…”

“…Assuming the availability of a priori data on existing radio navigation systems and the signals they use for navigation measurements, the present method can be used to analyze these systems for their accuracy and interference immunity. The modeling results show that the interference [24] has a significant impact on the accuracy of the navigation parameter measurement.…”

“…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.…”

“…These works confirm that poor quality satellite systems signals have a significant impact on aviation safety. The results of the Telemetry Accuracy Assessment presented in [24] show that the determination of the position of a flying object operating in an aeronautical communication network is significantly affected by how accurately the distance is measured between that object and other network users with a known position. Therefore, we investigated how to synthesize accurate DMEs that would allow distance measurement with maximum accuracy.…”

The Design and the Properties of a Jet Engine with the Rear Bypass of the Air

“…The above described comparison of these characteristics may be used for the quantitative evaluation of an increase in the thrust and the saved input power achieved with the examined engine following the application of the equipment for the rear bypass of the air. [14] This is documented in the relevant Figure with the data on the engine working in the operating point B. In this point, the input power for engines F e1 and F e3 amounted to 300 W. Engine F e1 exhibited the thrust of 250 g and engine F e3 exhibited the thrust of 379 g; the F e3 thrust represented a 1.516-fold change of the thrust F e1 , i.e.…”
