摘　　要：太阳耀斑是一种强烈的电磁辐射爆发,耀斑爆发时会影响地球磁场的稳定,造成电离层扰动,干扰无线电通信,并对航天器、卫星导航系统等造成影响。研究了太阳耀斑对船舶AIS通信影响,以中国东海海域为例,分析2024年5月初数次耀斑发生的前、中、后时间段的AIS数据。研究发现,船舶AIS数据本身传输的错误占比与太阳耀斑没有明显关系,但是根据AIS数据的船舶定位信息和时间计算得到的表观速度的方差在耀斑发生的前、中、后时间段有明显差异,结果表明太阳耀斑对船舶AIS的定位信息有较大影响。Solar flares are intense bursts of electromagnetic radiation that disrupt Earth’s magnetic stability,causing ionospheric disturbances,interfering with radio communications,and impacting spacecraft and satellite navigation systems.This study examines the impacts of solar flares on vessel AIS communication,focusing on the East China Sea.Using AIS data from early May 2024,spanning periods before,during,and after several flare events,we analyze the impacts on AIS communication.The findings show no significant relationship between solar flares and the transmission error rate of AIS data itself;however,the variance in apparent velocity,calculated from vessel positioning and timing information in AIS data,varies noticeably across these periods.This result indicates that solar flares have a considerable impact on AIS-derived positioning information for vessels.
