Yes, that's correct, but the interesting part is not the footprint, but the latency and variability of the dynamically routed paths you can obtain. That's what I simulated. I also made some modifications to how you'd normally route such a network, because the conventional approach wasn't fast enough if you have a wide choice of groundstations and the topology is continuously changing. The animations in the video are doing the route calculations in realtime once per frame of video; I was pretty pleased with those optimizations. One surprise, for me at least, was that there are paths where you sometimes want to relay via ground stations, even when the satellites have inter-satellite laser links. That's in the video towards the end. Edit: in response to the point you added about bandwidth: that's correct - there's no way the ground relay path competes with fibre on bandwidth. There are, however, many potential uses that require low latency and are not high bandwidth.
