Apparently Loran-C isn't seen as a viable alternative PNT source to GPS, unless upgraded to eLoran. The Coast Guard doesn't see benefit in upgrading the system and wants to get it out of their budget.
Tell that to Cam.They are up grading Loran-C to eLoran. That is going from tubes to solid state circuits.
The manufactors of GPS and Loran-C receivers are starting to combine them together for redunancy in electronic navigation. Which you should have and be doing is using two or more methods of navigation. Along with using Dead Reckoning.
Anyone that depends 100% on the GPS alone is a complete IDIOT!!
That is the most ridiculous statement I have heard in a long time.
My first resort would be another one of my 3 black boxes, then after that same way I do in my airplane, heading, speed and time and the MKI, Mod 1 Eyeball, keeping track on a paper chart. (I've had Lasik, most of you have just the MKI Eyeball).I'm quite the happy owner of my new-to-me Loran unit. Any navigator who fails to take advantage of all the navigational tools available to him is, yes, an idiot. While GPS is fairly reliable it is nowhere near as valuable as a compass or a fathometer. Loran sufficed for many years for off shore navigation and there's no reason to think that it will not continue sufficiently in that role.
GPS has contributed to the dumbing down of recreational navigators everywhere. My only question to those enamoured with it is, what's your back-up system? Just another $100 plastic black box?
I'm not sure I agree that marine charting is on a par with aviation charting and I defintely don't believe it is superior. Aviation charting is actually very precise as to hazards to aviation and not just in the location of airports. Some high end GPS units are now even offering synthetic vision, so you are presented with a 3D depiction of the surface beneath you if you had to land off airport. Yes, you'd still have to deal with structures and power lines when you got to visual conditions, but letting down the the muck knowing you are avoiding the "cumulus granite" of a mountain is a reassuring thing and I'm not sure I'd be as confident driving into a granite lined anchorage in fog using marine charting.Aviation charting is only more precise as to where the airports are located. Put your plane down anywhere else and you'll suffer the same inaccuracy or greater than any marine chart.
