On the other hand... With GPS-aiding its argued that high performance
INS-systems are not needed. The same performance will be reached with a
low cost GPS and a mid to low performance inertial system. So I doubt we
will have low cost high performance intertial sensors anytime soon.

Would it be possible with better antennas to receive signals from other

But that doesn't happend, right? *ironic tone*
With eLoran modernisation, there would be some chance of survival, but
obviously focus is on stripping down the suit if it
My impression is eLORAN is off the table. Since DHS is letting it go also.
Sextant, compass, and a good chronometer.
