COMBINED METHOD OF NAVIGATION INFORMATION PROTECTION IN UNMANNED AERIAL SYSTEMS CONTROL LINES WITH USING GLOBAL NAVIGATION SATELLITE SYSTEMS EPHEMERIS MODIFICATION ALGORITHM AND STREAMING CIPHER

Abstract

Force UKRAINE Abstract. This paper proposes a combined method of obtaining unmanned aerial vehicle coordinates directly in the ground control station coordinate system with using the real-time streaming encryption. The coordinates of the unmanned aerial vehicle are proposed to be obtained in the coordinate system of the ground control station, which is unknown to third parties. It is proposed to use the streaming cipher A5 / 1 which used in the GSM standard to encrypt the navigation information
