Wouldnt that be assuming the satellites were always exactly overhead of the receiving terminals? Also, the article claims operational orbits of 1,110km to 1,325km. To be fair, VOIP is pretty usable even with 50-100+ ms of latency and even higher. Intercontinental calls wouldn't be possible otherwise.
sorry I took the number from another comment and not the article.
At 1325km it's an extra 18ms so still well within the realms of usability.
given that they're aiming for 4425 satellites in total that would give them 66 loops of 66 satellites spaced 730m apart, meaning that when one satellite is overhead the next satellite will only be at most 1512km away line of sight.
