- If we really wanted to we could get the lag down to almost zero, using large
- numbers of ground stations connected by optical fibre (there are already
- commercial optical fibre cables under the Atlantic and Pacific). We could come
- pretty close using relay satellites in a low-ish orbit and a smart rerouting
- program (Iridium, in essence) or we could get down to 1/2 s using three ground
- stations, three geostationary relays and optical cables (cable to the right
- ground station, satellite to target).
