Global Navigation Satellite System (GNSS) is a critical technology that provides positioning using a series of satellite systems around the world. However, as the use of these systems has increased, so have the threats to their security. In this paper, we studied GNSS spoofing attacks and observed the effects of replay and spoofing attacks on real systems. Natural GNSS signals are acquired using Software Defined Radio (SDR) and the main strategies of GNSS spoofing, namely replay and spoofing, are analyzed in detail. As a result of the experiments, the deceptivity of the UBLOX M8N GNSS receiver and mobile phones is demonstrated. In conclusion, this study aims to examine the security vulnerabilities by combining the findings in the existing literature in a real system.
