Abstract

Global navigation satellite system (GNSS) has been widely used in various fields with potential security risks in GNSS applications. We briefly describe the causes of GNSS vulnerability and introduce typical navigation deception attacks. We also point out that satellite navigation spoofing interference is more harmful. The background and significance of GNSS anti-spoofing technology are stated to classify and summarize the means and measures of anti-spoofing technology in recent years. Finally, the advantages and disadvantages of current anti-spoofing technology are summarized to discuss the future research direction of anti-spoofing technology.
