Cyber threats prompt return of radio for ship navigation

Dear editor at Reuters, GPS uses radio too. Its not magic.

South Korea is developing an alternative system using an earth-based navigation technology known as eLoran, while the United States is planning to follow suit

 

The eLoran push is being led by governments who see it as a means of protecting their national security

Duh, you idiots.

To do so would require a powerful transmitter, large antenna and lots of power, which would be easy to detect, they add.

...which would be easy to detect and blow to smithereens.  Fixed that for ye.

I say power to them. If GPS can be hacked, and it's the most prominent link in the navigation chain, there need to be more alternatives available.

I read somewhere that the US Navy is bringing back navigation by dead-reckoning and using a sextant, as a backup for GPS. They realise that they have become too dependent on GPS.

Good. They should be able to do that. Just as aircraft pilots better be able to read a map and know where they're at and going to without radio signals.
