The Russians have their own GLONASS network as well.
Why would one use the ancient LORAN technology when there is GPS available.
So you think a LORAN system would not be vulnerable to attack?
I was of the understanding that LORAN was no longer in use. I may be wrong, but...
LORAN?
Now that’s a name I’ve not heard in a long time. A long time.
“Why would one use the ancient LORAN technology when there is GPS available.”
E-LORAN works better than a spoofed GPS.
“So you think a LORAN system would not be vulnerable to attack?”
Less vulnerable than GPS
There has been chatter about bringing LORAN back for about 6 years.
There are GPS outages, and some have been major, including one this year that caused some airline delays.
Just a handful f stations would provide the needed offshore capability. But wth government contracting, the cost could be huge.
Not much is happening with eLORAN right now. I suspect when Navy ships start running into each other, it will pick up. But only after determining that the collisions are not caused by watch officers not on speaking terms with each other.
LORAN is over. However there might be some foreign countries that still use it on a very limited basis. LORAN was disestablished in the early 90s as a means of navigation. The DGPS is a terrestrial based system that is used By Truckers, railroads, farmers (very large corporate farming applications), barges on navigible Rivers, large ports and harbors etc...
The Coast Guard maintains the DGPS system and is supported through MOU’s for the Department of Transportation and maybe for the Department of Agriculture as well.
But I am hardly the expert, however what perked my interest about the DGPS system was that large Farms that are so big that in order to hoe, disc, plant disc straight lines for miles they actually use the DGPS to keep their tractors on a track so that the farming is done accurately and no space is wasted because of variances in plow lines.
As far as trains go, trains move in what are referred to as “blocks” and there can only be one train in one particular Block. In order to maintain this safe distance trains incorporate the DGPS system so that they can maintain spaced in blocks and maintain the spacing. That does not explain errant drivers or impaired operators which cause accidents and other variants causing trains to wreck but these variances I do not believe are DGPS related but rather human error for the most part.
I took my sailboat up a river to a lake in FL and the lake had a bunch of old pilings, some submerged by a foot and a little handheld Garmin 76 accurately told me where the pilings were.
Really, a fixed stationary target is more vulnerable than one moving at 5 miles per second.
Hmmmm, I’ve worked on Navy missile and combat systems for 30 years and I’m going to have to disagree with you on that point.
General Patton once said, “fixed fortifications are a monument to the stupidity of man”, of course he was talking about ground combat, but the same is true when waging war in the electromagnetic spectrum.
The more agile and maneuverable the transmitter - (do not interpret that to mean in terms physical movement or location) - the more difficult it is to jam.
There are no LORAN systems, nor civilian GPS systems that I am aware of that employ any kind of anti-jamming technology, let alone the military grade technology to which I am referring. So I think, at least in time of a major war at least, anyone dependent upon civilian GPS or LORAN are going to be SOL. They’ll have to find a different way to navigate the oceans and the skies.
” that I am aware of “
That was obvious from your post!
Please do some homework and you will find that your two major assertions are not true.
“LORAN is over. “
But not E-LORAN.
Which two?
