it’s quite big, expensive, and not readily sourced, so when it’s used, it’s better that it’s really worth it. i don’t think cessnas need starlink, it would be worth it if it’s needed, but i think they might be using inertial + gnss. i heard that some drones had russian sim cards recovered so apparently sometimes gsm is used too. internet connection increases microwave signature greatly, and i’m not sure when it’s worth it, other than in cases where video feed is transmitted back and drones are guided manually, but that’s sea drones only. cessnas targeting refineries can work fine with gnss (+ maybe some crude tercom?) because refinery won’t run away
