Here, here

Be careful what you believe from the news media. They all serve whichever political party owns them, and will only raise your blood pressure. No such thing as unbiased news anymore.

Because unfortunately rising fuel prices will affect my soaring. But I agree - this is not a political forum. But talking about conflict and GPS - remember the days during the Gulf War when they degraded the accuracy of the GPS system. You can imagine the mess ii would cause if that was tried now considering how reliant we are on the incredible accuracy and reliability of the system.

Not commenting on this general thread.......
Not commenting on the sometimes GPS accuracy in the US.
Example......decades ago........seeing a track that went from Harris Hill to Europe and back.....in a few seconds. This while the glider and tracker were sitting on the grid at HHSC.......
I was there.
I saw the trace.
Pretty much NO WAY any government could cover that ground in that time.
I believe it was called, "military dithering" of the signal, because, government.

I believe it was interference from the unshielded ignition in Charlie Sprat's van as he drove by to the gate... but hey, that's my theory.

Charlie - We have seen that type of bizarre GPS trace in New Mexico on several occasions over the years. We had one logger trace a few years ago that had Howard Banks flying at hundreds of miles per hour to the SW and then back in a few seconds. Now, Howard always flew quite fast in his 27, but even for Howard, going supersonic was...well....unlikely. Being that we fly in New Mexico and given that Moriarty is not too far from Corona and Roswell (the crash site from 1947 is actually closer to Corona than Roswell) we usually figure it is just more alien interference (something we are quite used to), but it is possible that our friends at the White Sands Missile Range may have "something" to do with it.....maybe.....but.....I still think it is aliens....

GPS is owned and operated by the U.S. Government as a national resource. DOD is the "steward" of GPS, and as such, is responsible to operate the system in accordance with the signal specification.

Don't forget that GPS is a US military system.Â* It was not developed at
great tax payer expense just for the pleasure of a few glider pilots,
though I think it's terrific.Â* They can turn it off to us any time they
want.

Another benefit to the world from the evil empire.

They have "promised" not to turn off.

The US military built, owns, and controls it, but the user base has kind of gotten out of hand.

They might could turn it off any time they want once, but it might be a career limiting event.

If they caused a wide outage without a good reason, there would be a political backlash from the number of folks that paid for it being inconvenienced or worse.
