4G Broadband May Jam GPS

This is specific to the LightSquared 4G setup. Wimax and LTE installations already in place don't seem to be causing problems.
 
Wouldn't it be amazing if we had a terrestrial navigation system that would be able to give us GPS level accuracy with very little cost. Imagine a system like that. Oh wait, we had that (LORAN), and the government decided we didn't need that
 
Sounds like we better get "Bieber 6G Fever!"

The LORAN stations will need to be reactivated for the ADS-B system- except that it'll be all new hardware, software, power hook-ups, and probably locations too

Yeah, well, good thing we have people in charge who are at a minimum halfway intelligent. Never do anything smart, just make very shortsighted decisions.

I think that the LORAN system was run by the Coast Guard, at least the ones here in Alaska. They arent used for what they were designed for anymore. I dont know many, if any, major ships using LORAN.

Meh, according to all the "old timers" that used LORAN, it didn't work in the rain. I'd rather have the GPS. Not only that, but the LORAN infrastructure was difficult to maintain and expensive. I suspect that GPS provides worldwide coverage for a similar cost. Also, consider the accuracy of a GPS system, I've seen accuracies of as good as two meters... LORAN wasn't quite that good.

Not necessarily there junior (a 22 yr old saying "meh" over something he's never used....:) ). LORAN worked fine in the rain, I never had any problems with it. LORAN-C was a good improvement over the former LORAN-A and was good in capability.

I was thinking the same thing. Anybody who has flown with LORAN knows it isn't as accurate as GPS, unless you consider accuracy of 1 mile to be the same as a few meters.

Its the next and closest thing to GPS accuracy. Darn near very close. In descending order, GPS and LORAN accuracy were the top......LORAN being about 200m accuracy at best. Following that, you have TACAN at about 400m, an unaided INS at about 700m following 1 hour drift, VOR/DME and Doppler systems at about 1000m, and the old VLF/OMEGA at about 2500m.

So LORAN wasn't all that bad, all things considered.

And had we kept LORAN, we could have upgraded the whole system to eLORAN, for much less than the price of a single GPS satellite, and had accuracy to 10meters or so. Everytime I used it, it was great. Sure, may not have been something I wanted to use IFR, but just out and about in VFR conditions, it worked as well as a handheld GPS did.
 
Used to use the Apollo M1 navigator back in the 80's in a king air. Back then it was the greatest thing ever.
Will be interesting to see how the 4G threat pans out.
Funny how the FCC loves the big $$ companies.

Have alot of time using the Northstar LORAN system, and it was very good. Some who are trying to compare GPS accuracy in approach modes, to LORAN accuracy as an RNAV instrument in the enroute phase, which is all it was designed for......its apples and oranges. The LORAN was great as an RNAV in IFR, would often file /I with it.

Whoa, gramps! Let's not go too far, I rode in a plane with LORAN once that's practically like having flown it for 1000hrs right? ;)

But really? Never had any problems with it in the rain? At least a half dozen guys I talked to who had it in their personal airplanes all mentioned that it, "didn't work in the rain," huh. Interesting. What did you fly it in? The Hog?
