Abstract
This research provides a thorough examination of GNSS interference, with a focus on multipath effects and interference events. Field trials in London, a global analysis of interference incidents, and a specific exploration of the Chinese context were conducted to gather a diverse dataset. The research aims to enhance our understanding of GNSS interference complexity and its implications. Four main objectives include proficiency in interference measurement devices, rigorous field trials, a global assessment of interference events, and an examination of jamming and spoofing incidents in China. The CTL3510 GNSS Interference Detector was utilized in field trials, capturing interference signals and facilitating real-time monitoring. The study, conducted in high-traffic zones in London, collected data on signal strength, coordinates, and time stamps. The collected data was analyzed to uncover interference patterns, providing valuable insights into the multifaceted nature of GNSS interference and suggesting recommendations for global GNSS navigation system resilience and security.
