Abstract

This paper presents the results of the research in the field of anti-collision systems for small civil aircraft, which are not dependent on secondary radars and satellite navigation systems. The aviation communication network was used to design the anti-collision system. The simulation results manifested that the anti-collision system precision depended on the errors of synchronization of the aviation communication network. The precision of the anti-collision system is also influenced by the errors of the coordinates of individual aviation communication network users, based on which the system identifies its own position. The results of the simulation show that the dispersion of the positioning error σ2∆P by the ACS system varied in the range of 1.94 m2 to 503.23 m2. The simulation results confirm that the designed anti-collision system is operational in establishing its position against other FOs, with the distance from the given FOs being 50.0 km maximum. The main contribution of this paper are derived algorithms for the operation of an anti-collision system for small civil aircraft, in addition to the design of movement trajectory models of five flying objects which operate within the aviation communication network. The advantage of the anti-collision system is that it is independent of satnav systems and secondary radars. A significant advantage is the low cost of this system.

Highlights

The aviation development affects the growth of air traffic density which may lead to mutual aircraft collisions
The basic premise of creating an anti-collision system is that all flying objects (FO) work in the aviation communications network and each of the flying objects transmits their location information
In order to verify the sensitivity of the proposed algorithms to inaccuracies in measuring the distance of FO1-4 network users from anti-collision systems (ACS), we performed additional simulations for a straight flight of 1375 s and for a flight with a maneuver of 1375 s

Summary

Introduction

The aviation development affects the growth of air traffic density which may lead to mutual aircraft collisions. The given programs assume that global navigation satellite systems (GNSS) will have a dominant position in all flight phases. Great attention is paid to the issue of anti-collision systems (ACS). Most of the published works are devoted to the anti-collision systems of autonomous unmanned aircraft. Very few published works are devoted to the anti-collision system for the category of small aircraft. Some research results in the field of anti-collision systems are presented in [1]. The basic premise of creating an anti-collision system is that all flying objects (FO) work in the aviation communications network and each of the flying objects transmits their location information. An important condition for the operation of the proposed anti-collision system is a synchronous communication network
