Abstract
People are putting a great concern on Global Navigation Satellite System (GNSS) security while enjoying its convenience. GNSS is vulnerable and easily interfered by jamming or spoofing because of its opening signal structure, low signal power and complicated transmission environment, and this may lead potential security accidents or losses. Intermediate spoofing is an efficient spoofing attack method which is able to implement spoofing attacks without interrupting the regular functioning of user receivers and being noticed. This paper applies signal quality monitoring (SQM) techniques to GNSS intermediate spoofing detection and assesses the performance. The basic principle of intermediate spoofing attacking process and its detection are explained at first, which shows its effects on tracking loop status. Then, the techniques of SQM based on single correlator and multicorrelator are discussed respectively and the factors affecting the performance are analyzed and evaluated in detail, such as the number of correlators, SNR and so on. At last the paper summarizes the performances of SQM for GNSS spoofing detection.
