Identification Technology of Satellite Navigation Spoofing Signal

As satellite navigation systems become pervasive across industries, escalating spoofing signal threats jeopardize the dependability and protection of location services. This paper provides a comprehensive overview of methods for detecting Global Navigation Satellite Systems (GNSS)spoofing signals. By evaluating existing techniques using quantifiable metrics—including cost, performance, universality, and adaptability, the study systematically compares their strengths and limitations. Finally, the paper summarizes and projects future trends and potential research directions in spoofing signal identification technology, aiming to offer insights for subsequent research.
