Strictly speaking Omega Repair drones aren’t drones at all, they are more advanced E.B.K’s. Like E.B.K’s you use them from the repair icon on the navigation screen.

They will repair both Armour and hull damage, however like E.B.Ks they are consumable so one is used up each time you make repairs.

Since they’re repair kits not drones, you don’t need any drone control points to use them.
