That’s at least 20 ms of round trip time, realistically much more. Especially since it’s not geostationary so the distance to the closest ground station will in most cases be much longer than straight down. I would be surprised if the average ping is below 100 ms.

Probably still fine for most applications though.

Latency isn't really the issue here (lots of inference serving happening across oceans, which is probably 100-150ms RT), but bandwidth ends up becoming an issue for large scale transfers (mostly model weights, not the actual inference tokens/queries).

		With laser terminals you’ll get a few gigabits per second. That’s possible both between sats and to the ground station. Probably not cheap though.
