Abstract: The performance of GNSS spoofer, as one of the important tools of "navigation warfare", is directly related to the survival probability of the protected target. To provide an effectiveness evaluation with high confidence, the specific detection methods and calculation models of various indicators are established on the basis of a reasonable effictiveness evaluation indicator system and an evaluation test platform, and a basic method is proposed for equipment effectiveness evaluation. A theoretical evaluation threshold is set by using fuzzy comprehensive evaluation model, semi-qualitative and semi-quantitative grading method and weighted product synthesis algorithm. Based on the all-digital, half size hardware-in-the-loop simulation and full physical field tests, the effects of the main performance indicators on spoofing effectiveness are analyzed. The results show that the spoofing effectiveness can be improved by shortening the time of signal acquisition and increasing the power of spoofing signal and so on. Key
