This mod features Satellite Uplink Stations: Build and enter an uplink station like any other vehicle (enter key by default), and you'll gain the ability to remotely view any area as an "eye in the sky" thanks to your spy satellite(s) in orbit.
You can move the view around using the same movement keys (WASD by default), and when you're finished, click the "Terminate Uplink" button at top to return to controlling your player-character dude.
Although you cannot craft or remove/drop items while uplinked, nor interact with assembly machines etc., you can still use your deconstruction planner, explore any territory, and remotely direct trains.
