The spoofing capability of Global Navigation Satellite System (GNSS) represents an important confrontational capabil-ity for navigation security, and the success of planned missions may depend on the effective evaluation of spoofing capability. However, current evaluation systems face challenges arising from the irrationality of previous weighting methods, inapplicabi-lity of the conventional multi-attribute decision-making method and uncertainty existing in evaluation. To solve these difficulties, considering the validity of the obtained results, an evaluation method based on the game aggregated weight model and a joint approach involving the grey relational analysis and technique for order preference by similarity to an ideal solution (GRA-TOPSIS) are firstly proposed to determine the optimal scheme. Static and dynamic evaluation results under different schemes are then obtained via a fuzzy comprehensive assessment and an im-proved dynamic game method, to prioritize the deceptive effi-cacy of the equipment accurately and make pointed improve-ment for its core performance. The use of judging indicators, including Spearman rank correlation coefficient and so on, com-bined with obtained evaluation results, demonstrates the superi-ority of the proposed method and the optimal scheme by the horizontal comparison of different methods and vertical compari-son of evaluation results. Finally, the results of field measure-ments and simulation tests show that the proposed method can better overcome the difficulties of existing methods and realize the effective evaluation.
