Study on damage effects of lightning electromagnetic pulse on typical airborne GPS module

  • 摘要: 为研究雷电电磁脉冲对典型无人机机载GPS模块的损伤效应,通过仿真模拟和试验分析相结合的方法,获取了对GPS模块受雷电电磁脉冲暂态干扰与永久损伤过程的认识,并获得了相应端口的损伤阈值。基于对雷电流特性的分析结果,利用CST仿真模拟了雷击时,无人机内外产生的复杂电磁场环境和GPS模块线缆上耦合产生的感应电压。并对典型机载GPS模块的数据通讯端口进行了雷电脉冲注入试验。研究结果表明:随着雷电脉冲的不断增强,GPS输出波形受到削弱影响的程度不断加重,直至丧失位置信息传输能力并发生物理损伤。GPS数据输入端口的雷电脉冲损伤阈值为314.5 V,GPS数据输出端口的雷电脉冲损伤阈值为235.2 V。
