Description

technical field [0001] The invention relates to the field of broadcast communication, in particular to a system for real-time analysis and forecast of earth magnetic field disturbance. Background technique [0002] The earth's magnetic field is composed of three parts: the main magnetic field, the local anomalous magnetic field and the changing magnetic field. The first two change slowly and are collectively called the stable magnetic field. The changing magnetic field is also called the disturbance field, which originates from the space current system. It can undergo drastic and rapid changes under complex and variable interplanetary conditions. It is closely related to human life. For example, in the case of strong magnetic disturbances, especially during geomagnetic storms, it may cause malfunctions of space vehicles, interruption of communications, and destruction of power systems. Therefore, disturbances in the geomagnetic field directly affect human life and producti...

AI Technical Summary

Problems solved by technology

Although there are hundreds of geomagnetic stations around the world that continuously observe changes in the geomagnetic field, it is currently difficult to summarize the observation data in different regions and calculate a unified indicator of the overall change degree of the geomagnetic field in real time, especially when the communication link is interrupted. period

In addition, medium- and long-term geomagnetic disturbances have certain regularities, but their changes are complex and diverse, which cannot be used correctly and effectively in conventional forecasts in the past
