what role does magnatism play in ground control of artifical satellites

Artificial satellites have given a significant contribution to enrich our Earth’s magnetic field knowledge. The importance of magnetic field measurements from satellite altitude is straightforward. Satellite data furnish in fact a global covberage of the Earth’s magnetic field morphology in a short time compared to the Earth’s magnetic field time variations, for example the secular variations.The Earth’s magnetic field shields us from a lot of the ionising radiation that comes from space.Artificial satellites have many uses, including telecommunications and weather predicting, but can be disrupted by solar flares from the Sun.
