Re: UK has the resources
In principle eLoran is not nearly as accurate as GPS-like systems, but in practice it is good enough for many activities where 10m or so is sufficient (like not being lost at sea).
Main advantage is the high power low frequency system is harder to jam over any significant area, and it would not cost billions to cover the UK. But using it world-wide has the problem of enough ground based transmitters and their running costs (maintenance, power).
As a fall-back for accurate timing and frequency control in the event of GPS outage for whatever reason it would be great, but again with a small market it is unlikely to be developed and unless it is forced upon operators of critical infrastructure then they won't spend the money to add resilience.
