Wow this is a big area
Wow this is a big area, any idea why it is so big? Does anyone know if this normal and what has happened before with these tests? thanks

It's a huge area, extending into the San Francisco Bay Area.
If you have a later model (within the last year) iPhone or iPad with GPS, they claim to also receive GLONASS signals from the Russian system. Don't know what they do if GPS and GLONASS disagree widely. Other smartphones also appear to receive GLONASS. |
centered at area 51/groom lake, nice

Perfect, that looks like 75% of my trip down to LA during that time frame. Looks like I better flight plan Vor to Vor. I have lost GPS on my 430w north of st George one year, it was a shock as I never thought that would happen. I was glad I had the nav on it and the Sl30. I did not have the IPad back then. We will see what it does this time.

Great. This is happening when a bunch of us are converging on Madera, CA for the West Coast Formation Clinic. Looks like it's also going to be the "West Coast Dead Reckoning Clinic".

Last two times ... we just went over the top of it all. That's an option if you don't have to go into it. Quote:

Did I read this wrong? The biggest interruption is AT 50 feet. Times are sporadic not to exceed 2 hours at a pop. While this is noteworthy, it doesn't seem like a huge inconvenience.

NSAWC is the Naval Strike and Air Warfare Center. That should give you some clue as to who is doing the testing.
|
Well, I'm guessing that long range missiles may have some form of guidance in them, and I think there is a country currently threatening to attack our great country... I wonder what this could be about?
|
Not much concern
These things pop up all the time, I've never experienced any gps failures. I've asked the guys at ABQ center and they said they don't see any problems with coverage during these tests. It could happen, but not likely to effect a whole flight.

I understand GPS is a US military system. But the FAA plans to depend solely on GPS in the future, not to mention millions of autos, hikers, etc. My RV won't have VOR capability (except maybe a handheld NAV/COM) since it costs thousands more for the radio. Something has to be worked out between the military and civilian uses. |
