Went over past EMP topics and this really hasn't been touched.

A high altitude device causes a continent wide disruption from EMP. Whether this happens or not is open to conjecture. This is the sit X project. Basic knowledge provides something will happen to ground based communications and power supplies. A person can protect somethings from this.

My question pertains to satellites. Would a geostationary satellite several thousands miles from the event be disrupted to a non-working state? I'd think that the protection from solar wind and solar event would provide a certain amount of protection. What are your thoughts about sustained satellite communication after an EMP event affecting land based communications.

I suppose that would be open to conjecture as well. My personal belief is that the fear of EMP destruction causes us to exagerate it's power. Still, I try to keep as much of my electronics as I can in metal boxes within metal boxes. Some things are just too potentially devastating to be wrong about.

As to the satellites,,,I'll gladly give up my gps capabilities if it costs big brother the ability to use satellite surveillance against me.

Not nearly enough is known about emp. People tend to relate it to electrical properties and in my opinion that is wrong. It's about magnetic field (inductance), not electrical properties. Shielding is the key. Not grounding. How do you change a magnet by grounding it? It's still a magnet with the same force. As I understand it, magnetic properties are as relavant in space as they are in the atmosphere.
