Comparative Analysis of Single Antenna and Antenna Array for GNSS Jamming Resilience

Global Navigation Satellite Systems (GNSS) are critical in navigation, communication, and timing applications. However, their vulnerability to intentional interference, such as jamming, poses a significant threat to the reliability and security of GNSS-dependent systems. This paper presents a comprehensive comparative analysis of the jamming resilience capabilities using a single antenna and an antenna array in the context of GNSS receivers. This paper investigates the effectiveness of using single antennas versus antenna arrays in mitigating the impact of jamming signals on GNSS receiver performance. The data was simulated using Skydel simulation software to model a land vehicle trajectory. The outcomes highlight the advantages of employing an antenna array as the initial defence against jamming attacks.
