A Method for GNSS Spoofing Detection Based on Sequential Probability Ratio Test

D. Yuan, H. Li, M. Lu

Abstract: Nowadays, an increasing number of applications and services are based on the Global Navigation Satellite System (GNSS). GNSS signals are vulnerable to interference, jamming and spoofing. Among them, spoofing attack is extremely deceitful and destructive, because it can result in misleading time and position error. Hence, reliable spoofing detection is of great importance for many critical applications and services. Since PN-code acquisition is the first step of baseband signal processing, successful spoofing detection at this stage is timely, and alarms can be raised as early as possible. Therefore, a new method for spoofing detection at the acquisition stage based on the sequential probability ratio test is proposed in this paper. And performance analysis and evaluation of the proposed method is presented as well. At last, simulation results are provided to demonstrate the effectiveness of the theoretical results.
