Garry,

I think you mean an alternative to GNSS (of which GPS and Galileo are examples).

For maritime the alternative is CN + Radar (+DR + depth+ pilotage etc)
, for aviation I understand it is inertial + radar + maybe still VOR.
For road vehicles it is map +"wind down the window and ask directions"
I suppose!
