今年是第25个太阳周期中最活跃的一个阶段,地球或将面临强大太阳风暴的袭击,全球定位系统等轨道卫星将遭受严重威胁。太阳周期是太阳磁场活动的规律性现象,将会导致地球电离层环境出现改变,电离层受到干扰。众所周知,全球定位系统的信号依赖空间传输,而混乱的空间电磁环境可能导致导航信号出现严重问题。当前运行在轨道上的人造卫星应用技术还未经历过太 This year marks the most active phase of the 25th solar cycle, and the Earth may face a powerful solar storm that will threaten the orbiting satellites such as the Global Positioning System. The solar cycle is a regular phenomenon of solar magnetic field activity, which will lead to the change of the Earth’s ionosphere environment and the interference of the ionosphere. As we all know, GPS signals rely on spatial transmission, and the chaotic spatial electromagnetic environment can cause serious problems with navigation signals. The satellite application technology currently in orbit has not yet experienced too much
