eLORAN

You can fit an F-16 in your garage? :P

I'd love to know more on avionics, I still have an idea of taking an old comm radio out of an a/c and connecting it to a speaker to listen to LHR approach.

Let's just say the last 10 years have been a really amazing ride. I never thought I'd build an integrated GPS/INS nav system that could be bolted on to a F-16 in my garage... but that's what I did for my Master's thesis. We were getting centimeter-level accuracy horizontally from components we purchased commercially using a credit card.

Ok, Thanks for the reply. I don't know much about thestrengths and weaknesses of cell phone signal, but I do believe the limits are a short range. ???

GPS, for all the launch and support costs, has become so much more than just a navigation source. Fields are plowed and harvested using differential GPS, heavy equipment can build roads with automatic positioning, and the ability to track an item in a logistics train down to the meter has enabled "Just in time" logistics to flourish. Not to mention all the mobile technologies that use GPS.

Loran is ok... but its just an antiquated navigation scheme. It's like saying "let's bring back A-N beacons!" If we felt we needed a back-up navigational network, a mesh network using cell towers would be cheaper and just as effective at this point.

LORAN is cheap backup, that given 10 years of people upgrading equipment, could be on everything. Build a receiver that gets bot GPS and eLoran. eLoran would give us the capability for at a minimum LNAV approaches. VOR's are antiquated, yet they aren't being trashed for no reason. Same with ILS.

All of those techonlogies you listed could have a combo receiver, GPS/eLoran when its time to upgrade/replace them. Heck, I've got a bluetooth GPS that's GPS/GLONASS.

Plus throw in how relatively easy GPS is to jam versus Loran, and I see a great case for spending the money to use the system again.
 
I got my IFR ticket with a single vor and a kln88 loran it was a good unit and very accurate but I doubt the U.S. will turn it back on....mucho $
