You gonna get lost. lulz
Have a back up plan huh? Map?
That's according to a flight advisory just issued by the FAA, which warns pilots that their GPS signal "may be unreliable or unavailable" due to "GPS tests" that the Department of Defense will be conducting between January 20th and February 22nd.
I have a two stage backup plan. Stage one, have map. Stage two, don't let wife read map.Originally Posted by KG4CGC
Hell, I can't drive upside down anyway.
I'm betting there's a back-up plan with people on the runways guiding the way with laser pointers.....
Why,driving into a brick wall at 60 miles per hour, would I expect it not to hurt!
Walk and Talk like a Canajun!!
There is nothing strange about this. DoD needs the system for that time. So for that time period you backup everything with other navigational systems. Thhe Dod needs the system. And when the Dod wants something they GET IT!!
I keep my 2 feet on the ground, and my head in the twilight zone.
Of course they get it if they need it. The DoD owns the system :)
People have been flying on instruments without GPS for a very long time. Airways and VORs work very well. Though I am told they are not replacing NDB units as they go down, the old ADF system is still available over much of the country. Doan need no steeenking GPS.
Yeah, 3 VOR's and you are just as accurate as GPS. 2, and your damned close. 1 + Dead Reckoning puts you rather close.
I know the alert said it could be inaccurate, but I'm wondering how? You can't take part of the system down, so I'm at a loss as to what is going on, since it needs to be damned accurate while used in military operations (Which are ongoing)...
Hello.
GPS is actually 2 complete systems.
The low accuracy side is intended for a quick fix and the military side is encrypted.
But the FAA has a solution that works better than even the military side.

Couple that with ADF and an FM-BCB ADF and one can get a fix of as little as 2 inches, and that is how some survey equipment works.
Want an even closer fix? set up a base with your rover.

Even without GPS you can get a fix of around 200 feet with ease.
AM radio stations can provide that level of accuracy.
But, nearly all of the good GPS receivers now have WAAS.

Add to that the Russian system.

And there is no reason for an outage.
A laptop can easily be equipped with a Glonass receiver as well as a GPS/WAAS unit and use both.
dod can fooch the gps readings for non dod gps users while keeping their users accurate in times of conflict, but Russia has made a gps service and China likely has one too so if the dod fooches their gps the only folks who will be fooched is, once again, the US citizen
GPS is ONE system Rudy. A fudge factor is sent on every signal, which is then removed by military GPS units with the proper keys loaded by a K1C unit.
They do it daily, every day. So, I'd hazard your idea is correct, they are playing with the fudge factor to see how much of one they can insert before their own devices suffer.
