The UK Government has confirmed that it will no longer use the EU's Galileo satellite system for defence or critical national infrastructure after Brexit. Instead, the UK will explore options to build its own global navigation satellite system. It will also work with the US for continued access to the GPS system.

The UK Government set aside GBP 92 million for the plans in August, with over 50 UK companies expressing interest in the project. A series of key contracts are now being tendered, with plans to use UK Overseas Territories and Crown Dependencies for the global network of locations required for the ground infrastructure and worldwide coverage . The Government wants any new UK system to be compatible with the US GPS network so that they could provide vital positioning data if the other system was subject to a malicious attack.
