You can climb up the barrier wall with another hook (half-hook preferably, so you don't also lose it) and detach the hook from the drone. The drone should make it's location obvious, so at least you have that going for you.
Don't know why I didn't consider doing that, thank you! That said, I still think a drone reset debug command should be implemented in case something breaks with it. Just because the whole game relies on you being able to use the drone
