Looks like a solution may be on the horizon:
"Scientists in the UK claim to have found a way to mimic the functions of GPS without sending anything into space.
Known as a ‘quantum compass’, this revolutionary method would use the subatomic effects on Earth’s magnetic field and could one day be employed in smartphones.
But GPS is also limited with regards to submarines – when they dive underwater it no longer works.
This means that when a submarine eventually resurfaces, efforts to locate it can be out by more than half a mile (one kilometre).
A quantum compass would, apparently, reduce that inaccuracy down to just three feet (one metre)."
