Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what assessment he has made of the defence implications of a satellite navigation system for the UK.

UK Armed Forces rely upon accurate Positioning, Navigation and Timing information for a variety of critical applications. We have privileged access to US GPS, the world's foremost GNSS system. The Ministry of Defence is committed to a systems-of-systems approach to managing PNT vulnerabilities; we are working across Government, including the UK Space Agency, to develop options for UK Assured PNT to maximise return on investment and meet Critical National Infrastructure requirements.
