Galileo includes Public Regulated Service (PRS). PRS has both military and civilian uses. Civilian uses include safety critical applications like autonomous cars, energy grids, air traffic, military and commercial drones, trains, some emergency services and so on. It's jamming resistant highly secure system that many commercial future systems depend on (even the open services in Galileo are spoof resistant). Since UK will be closed out the development of PRS, UK thinks it's not going to serve their national interest to rely on EU.
