Electronic Warfare Aspects of Satellite Navigation Systems

Abstract

The Global Navigation Satellite Systems – GNSS vehicle mounted and handheld receivers are vulnerable to jamming (overpowering GNSS signals) and spoofing (making GNSS receivers to calculate false position). The main aim of this article to overview three parts of electronic warfare in terms of global satellite navigation systems. This article outlines some methods of the threats to GNSS and presents some methods and devices for detection of jamming and defence GNSS systems.
