A new framework for GNSS spoofing detection based on signal phase and structure

Spoofing interference casts significant threat to the GNSS receivers making the enhancement of spoofing detection capability a crucial issue. Detection performance of traditional SQM method encounters evident degradation in interference process. Utilizing phase feature and specific structure of spoofing signal, a new spoofing detection framework has been developed to determine the existence of interference. Preliminary experimental results in TEXBAT indicate that this method owns great potential in spoofing detection, maintaining stability and accuracy in different stages of interference.
