Abstract
In this paper, we describe the design of the on-board anti-collision system. We assume that all flying objects work in the aviation communications network and each of the flying objects transmits their location information. The basic condition for the operation of the proposed anti-collision system is asynchronous communication network. Each network user is precisely determined by the time of broadcasting communications messages. This means that every user who works on this network has information about the time of broadcasting signals to other users. Based on this, we have designed an anti-collision system that will work on the principle of relative navigation.
Highlights
When designing the anti-collision system model, we assumed that if we know the position of at least two points in space and the distance of these points to an unknown point, we can calculate the position of the unknown point
If we know the coordinates of individual users of the aviation communication network (xi, yi, zi) and the distance of the anti-collision system from these users, we can determine its position P with coordinates (x, y, z)
Based on the principle of relative navigation, the anti-collision system is able to determine its position vis-à-vis other users in the aviation communications network
Summary
When designing the anti-collision system model, we assumed that if we know the position of at least two points in space and the distance of these points to an unknown point, we can calculate the position of the unknown point. We anticipate that, by transmitting communications messages by individual network users, our anti-collision system will know the location of those users. It will be able to measure distances to these users because we have the time to send communications messages by individual users. RelNav positioning is based on measuring the distances to the broadcast sources by measuring the arrival time of the signals from these sources. The position is most often expressed in geographical coordinates in WGS-84. We will use a rectangular coordinate system (ECEF) to design an anti-collision system [1]
