It was just a short time ago these systems were decommissioned because the were "old technology" and redundant in the light of GPS navigation.

Old tech
Ah, just give them a good chronograph and a sextant and they should be all set!

eLORAN--
Not as old as the sextant, but definitely the revival (and extension) of an older technology...
...and one the U.S. chose to abandon, even as it was being extended and revived overseas...
...because why would you need it anymore when everybody has GPS?
(how about for the same reasons ships still carry charts?)

Loran
Is this the Loran that we used 50 some years ago on the Navy ships? IIRC, the QM spent 15 minutes getting a fix.

It would be similar. Of course 50 years ago you only had analog computers that relied on synchros and servos. All that work would be done by a digital computer so the updates would be almost continuous.

Solar weather effects?
"Last said all GPS systems run the risk of signal loss due to solar weather effects."
When's the last time that happened? I'm not sure I remember it.

Same holds true with the analog devices
I can't read my map at night when the sun is on the other side of the earth...

Navigation
Cruise ship crew are required to be able to chart their position on a paper chart using a sextant. It's not used unless needed (likely has never happened) but they ARE required to know how to do it "just in case".

If I were captain I damn well would have an accurate paper chart with the ship position at all times and weather data too. HMS Bounty.

Always good to have some candles if the lights go out. As Sandy has proved Technology is only as good as the power that supplies it.
Told ya
'nough said!
Indeed.

I would fully expect to see some people 'stuck' on escalators in a power failure.
is that like

Is that like the lady that called AAA to unlock her convertible after she had left the key inside with the top down?

LOL!
That reminds me of when one of my neighbors did a similar thing. She left the keys in the car, running. It was a GMC SUV of some sort. She's digging through her purse looking for Onstar's number... I saw the open sun roof, and dropped her 5 year old into the car through it. So much for technology...
