摘　　要：为了研究战时全球定位系统(Global Positioning System,GPS)信号变化特点,分析GPS信号变化与美军军事行动的关联性,使用RTKLIB软件以载噪比、可见卫星数DOP值、定位误差为基本指标对美军在叙利亚发起的两次军事行动期间的GPS信号进行分析,分析结果显示美军两次军事行动期间GPS信号均出现了L2频点全球功率增强以及叙利亚GPS跟踪站DOP值的异常变化,载噪比与DOP值的变化与美军军事行动之间有比较明显的关联性,可以作为分析美军军事行动的重要指标。In order to study the characteristics of wartime GPS signal changes and analyze the correlation between GPS signal changes and US military operations,RTKLIB software is used to analyze the GPS signals during the two military operations launched by the US military in Syria with the basic indicators of load-to-noise ratio,visible satellite DOP value and positioning error,and the analysis results show that the GPS signals of the US military during the two military operations have the global power enhancement of L2 frequency points and the abnormal changes of DOP values.There is a clear correlation between the change of the noise ratio and the DOP value and the US military operation,which can be used as an important indicator for the analysis of the US military operation.

关 键 词：GPS 载噪比 DOP值 定位误差 RTKLIB
