What would happen if all the GPS satellites failed?
Sol asked:
If all the GPS and communications satellites failed (extra strong solar flare/EMP etc), do ships captains/crew still have the skills to navigate by compass & sextant, would lighthouses have to be recommissioned?

Can anybody recommend a good bare bones handheld GPS receiver?
Privratnik asked:
I’m looking for a GPS receiver that I can use for back-country navigating in third world countries where no good commercial GPS maps are available. I need very basic compass and waypoint features, but no mapping.
Durability is a must!!!
