GPS Spoofing Detection via SNR

Abstract

Nowadays, the use of GPS has penetrated everyone's daily life, so the safety of GPS signals has threatened all of us. Since the portable GPS spoof was proposed at the Black Hat Conference, the cost and threshold of GPS spoofing have also been getting lower and lower. However, many strategies for anti-GPS spoofing may need to add new hardware equipment or require powerful computing power. We aim to use the smallest possible cost to complete the purpose of GPS spoofing detection. In this article, we have designed There are many different detection schemes, and their detection delay and accuracy are different. To prove their feasibility, we did a real experiment. We evaluated the performance of the system based on the experiment, and the results show that the system accuracy is as high as 98%.
