Re: LEO Latency
Propagation of light in a vacuum is 299,792 kilometers per second. At 350 km, a signal would take a minimum of 1.167 seconds ONE WAY. Any signal would have to be beamed to the satellite and then transmitted back to your earth-bound receiver, so 2.334 seconds as a theoretical minimum, not counting any latency getting from the ground station to the host website from which you are receiving the data.
So you are off by a few orders of magnitude.
