eLORAN

[moodychief]

Does anyone know the specifics behind the space-based eLORAN the FAA is looking at?

[carusoam]

If we need to go back to ground based navigation eloran will be the next gen...

I hope to catch up to the existing system before they switch to a different system...

Hmmm, that link is for Irish and UK boat pilots going into major ports . . . As stuffy as the Brits are about GA, do you ever see it moving beyond ships? Our Buddy shut down the perfectly-functioning, still new LORAN C network here, as if the $100 million annual budget would make a difference in his trillion-dollar deficits . . . But it WAS something concrete he could point at . . .

i wouldn't hold your breath for eLORAN to leak over from British ships to anything approved by the FAA, at least not during the useful lifetime of the technology and systems.

Sorry to be such a pessimist.

Whne I got my PPL LORAn was the hot new thing.  I only flew one plane that had ti and rarely used it since I was usually not going much past 100nm.

 

For those that id use it was there dead zones sort of like ADS-B WX and traffic data?

Would the new system work halfway across the ocean or in western states like GPS does?

 

Just curious.

Glad they did shut it down.  $100 million is not a small sum.

The way I read A's article, it is a repackaged LORAN-C with a step away from the short comings of the old system. My guess is that some countries may be worried about relying on a U.S. or Russian based GPS system and are looking for an alternative. As well, it appears the U.S. Is looking for a backup to GPS.

Now where is that STS LORAN receiver I pulled out of my plane?!

The LORAN-C chain was maintained by the US Coast Guard.  Their budget was around $17M per year to operate it the last few years it was in service.   Compare that to the FAA's budget for maintaining VOR/DME, which is about $500M per year, and the DoD budget for GPS (probably in the $1B per year range) and I wonder why we shut down a totally independent navigation system that was basically free compared to the alternatives.

What is even more interesting is that they are looking at it again to safeguard against the potential risks and shortcomings of GPS navigation. I was amazed to read how little it takes to knock out GPS signals.

Wasn't that the whole thing with someone's Satellite High Speed Internet service? a politically favored someone? Can't recall the name now, but it was big in the news about two years ago, being pushed through by DC despite being next to and bleeding into the GPS transmission frequencies.

I have three on the shelf in the hangar if you want them....

Loran had to turned off, Garmin didn't make Loran receivers.

Same here. I was a renter then and had a marine portable Loran receiver. Had to actually type in the coordinates for waypoints, but it worked unless flying around thunderstorms when it would sometimes have a hard time keeping a lock.

Ha! Spoiled young whippersnappers.  

First Loran C I saw was on a shrimp boat (the Vangie out of Port Mansfield, Tx) in '73. It was the size of a small refrigerator, had an oscilloscope screen, and you had to dial up and match spikes on the screen to get the TD's.  We had overlay maps to plot them on. After years of dead reconing, we thought it was magic.  

By the early '80s Texas Instruments had a unit that would fit on a small boat, cost about $1000, and display the TDs. We thought it was wonderful. I still remember some of the TDs. The 11214.7 line crossed the 100 fathom curve at a canyon, great place to Marlin fish. 

Loran was never as accurate as GPS is now. Maybe within 30 yards at best if you used numbers your machine generated, and your alternator was quiet.

Vor decom doc on AOPAs site is marked as not to be shared outside the FAA.  Glad our buddies at the Gubmint know what they doing.
