| Abstract: |
| The spoofing against the Global Navigation Satellite System(GNSS) has the characteristics of strong concealment and high harm,which threatens the security of GNSS.First of all,the principle and key technologies of self-consistent and replay spoofing are introduced.Secondly,the existing spoofing detection and mitigation methods are summarized and classified,and the existing technologies are analyzed in detail from the aspects of cost,performance,complexity and research focus.Thirdly,a comparative analysis is conducted on existing spoofing attacks,detection,and suppression methods based on performance and cost.Finally,the issues worthy of attention in spoofing defense in the future are prospected,in hope of providing ideas for follow-up related researches. |
| Key words: global navigation satellite system(GNSS) spoofing spoofing detection spoofing mitigation |
