Research Status and Prospect of Evaluation Indexes and Evaluation Methods of GNSS Spoofing Efficiency

With the electromagnetic environment becoming increasingly complex,satellite navigation application is facing severe challenges. Global navigation satellite system( GNSS) spoofing technology, as one of the core technologies of navigation countermeasure, has gradually become a hot research direction globally. With this in view, the GNSS spoofing equipment based on spoofing technology is leaping from the verification stage to the application stage. Effectiveness evaluation of its efficiency and selecting the equipment with excellent performance can not only enhance modern navigation countermeasure, but also largely determine the success of target tasks. As the theoretical basis for the research of effectiveness evaluation, firstly, evaluation indexes and evaluation methods of GNSS spoofing efficiency of application background and research progress are briefly introduced in this paper. Secondly, the research status of evaluation indexes and evaluation methods of GNSS spoofing efficiency by both domestic and overseas scholars are analyzed and summarized. Finally, its deficiencies and development trend are expounded.
