Quite where this takes us all is not entirely clear because the overall systems are already set up and the focus is on a growing set of added value and military/security services as well as considering how the vulnerabilities might be addressed.
For the UK to go it alone on this is frankly a bit daft. The role of the 5 eyes might have merit in some aspects because there the issue is all about managing threats from Eastern Europe, China, Indian subcontinent and South America. However co-operation with the Galileo EGNOS programme would get those tools deployed a great deal quicker than the proposed DIY approach and with less reliance on the USA which could well be back in Trump's hands in four years time....
