摘　　要：本文利用实测数据对2018年4月美国军事打击前后叙利亚地区的GPS性能进行了分析,结果表明,战前距离大马士革最近的BSHM测站的GPS信号受到干扰,其定位性能受到影响。作为应对措施,在此期间,GPS进行了L2P码信号增强,增强后干扰的影响减弱。In this paper,the measured data is used to analyze the GPS performance of the Syrian region before and after the US military strike in April 2018.The results show that the GPS signal of the BSHM station closet to Damascus gets disturbed before the war and the positioning performance is affected.In respond to this,the L2P code signal is enhanced by GPS during this period and the interference is weakened after that.
