摘　　要：海上事故发生后,第一时间需要确认的就是遇难人员无线电求救信号的具体位置,再进一步展开救援。由于海上不可控因素的影响,我们无法直接获取落水人员的具体位置。简单无线电测向仅知道求救信号的方向而不知道距离,我们很难得知遇难人员的准确方位。本文通过利用H MC5883 L电子罗盘和ATGM336HGPS定位模块与无线电测向接收机的结合,对接收到发射信号后实现精准定位进而实现高效搜救。After the maritime accident,the f irst thing to be conf irmed is the specif ic location of the radio distress signal of the victims,and then further rescue.Due to the inf luence of uncontrollable factors at sea,we are unable to directly obtain the specif ic location of the person falling into the water.Simple radio direction f inding only knows the direction of the distress signal but not the distance.It is diff icult for us to know the exact orientation of the victims.Through the combination of HMC5883L electronic compass,ATGM336HGPS positioning module and radio direction f inding receiver,this paper realizes accurate positioning after receiving the transmitted signal,so as to realize eff icient search and rescue.
