What do you mean?<p>Satellites are either geostationary or not. If they are not geostationary you need a network of them and complex ground equipment. If they are geostationary, they incur a ping latency of a few hundred milliseconds making them worthless for modern mass Internet usage. Either way, bandwidth is quite limited compared to what is flowing through fibers today.<p>Also: I am pretty certain US, Russia and China by now are able to kill satellites at will, geostationary or not.
