摘　　要：为了更准确的实现对导航干扰的性能评估和功能验证,结合近期美英法空袭叙利亚真实战争案例,通过RTKLIB软件解算典型地面跟踪站的IGS观测数据,并利用信噪比、可见卫星数、PDOP和定位精度4个重要指标来定量分析空袭期间GPS信号受干扰情况。研究结果表明:离大马士革最近的BSHM地面站在空袭当天有两个时间段GPS信号受到了较严重的干扰,此干扰效果评估指标体系和评估方法可以有效的判断GPS信号的受干扰情况。For more accurate implementation of the performance evaluation and function verification of navigation interference,this essay combines with the recent air attacks of US,British and French on Syria real cases.And the RTKLIB software was used to solve the IGS observation data of typical ground tracking stations,Four important indicators such as the signal-to-noise ratio,visible satellite number,PDOP and positioning accuraly are used to quantitatively analyze the interference of GPS signals during air strikes.The research results show that the GPS signal from the nearest BSHM ground station in Damascus has been seriously interfered with by two time periods.The interference effect evaluation index system and evaluation method can effectively judge the interference of GPS signals.
