Worth noting these will be low-orbit satellites like StarLink (possibly even lower), which also gets over the latency problem (Starlink Satellites are at ~550km altitude - on the outer edge of the thermosphere, with a return trip latency of ~45ms; Geostationary satellites are 35,786km altitude, with a return trip latency of ~250ms)
