Problems solved by technology

[0003] At present, the most direct research method for the magnetic storm phenomenon in the Earth's magnetosphere is to launch satellites for deep-space exploration, but deep-space exploration has shortcomings in the aspects of single observation point, limited orbit, long observation period, and accidental data acquisition. Therefore, There are certain limitations in simply using satellite detection to study magnetic storm phenomena in the Earth's magnetosphere
