摘要: 对2019年6月美伊冲突事件中的GPS功率增强进行了分析,具体从接收机类型、天线类型以及卫星型号三部分对GPS P(Y)码的功率增强进行了分析,分析表明,采用不同类型接收机的测站,其功率增强值明显不同,而采用不同类型天线的测站,其功率增强值相差不大;此外,在接收机或天线类型相同情况下,同组并址站的相同类型的卫星功率增强值对比结果呈一致性.

Abstract: This paper analyzes the GPS power enhancement in the US-Iranian conflict in June 2019, and analyzes the power enhancement of GPS P(Y) code from receiver type, antenna type and satellite model. The analysis shows that the power enhancement values of the stations of different types of receivers are significantly different, while the power enhancement values of the stations using different types of antennas are not much different. In addition, in the case of the same receiver or antenna type, the same type of satellite power enhancement value comparison results of the same group of co-locaion-stations are consistent.
