Contemporary GPS Security Mechanisms

Abstract

GPS (Global Positioning System) plays a big role in day to day activities. From navigation to tracking devices, all are dependent on GPS. As the attacks on GPS have increased so the review of GPS security plays a vital role in research. This paper looks at different spoofing generation methods. The idea is to discuss the single antenna, multiple antenna and other factors that are susceptible to interference. Based on the type of vulnerability the solutions are described in detail. This paper focusses on the current anti-jamming and anti-spoofing GPS mechanisms. This paper presents a comprehensive analysis of all the techniques along with the pros and cons of each method.
