These activities have been cancelled. The NOTAMS will be removed shortly. As one of the organizers for the Nephi event I have been communicating with folks from the Utah Test Range about any GPS jamming activities and they told me this morning about the cancellations

The notams are still up as of this morning. Sure would be nice if they
took them down.

Here's an easier url to deal with: http://tinyurl.com/prds7nr

Duration appears to have been reduced. Last instance now 6/11.

I flew my Stemme from Minden to Moriarty yesterday (after a week of
soaring!) and had GPS coverage for the entire trip. Guess I got lucky...

Now showing activity through the 12th. If this stuff really has been
canceled, somebody forgot to tell the notam writers.

You should be loading up on lotto tickets, Dan.

Interestingly, I had a decent flight yesterday, everything seemed to be
working fine. Up until just before the landing pattern, when GPS
altitude indication started flipping between correct altitude, and 0.

It was just a couple minutes around 23:19 zulu, 5:19 pm local. IGC file
uploaded to OLC, no problem, you can pull it from region 9 US. Got the
two green dots from OLC, plane didn't start doing Dutch rolls or
anything, but it does seem strange that my trusty 302 would choose June 9
to start acting up. Viewing the file on SeeYou shows what I was seeing
in the cockpit.

Down low in Colorado, wouldn't have thought the canceled China Lake
testing (whose notams never seem to go away) could be involved here, but
who knows?

Hi Dave,

Were you within 300 nm of Alamogordo? I haven't checked the notams, but
you could have gotten zinged by some of the continuous testing which
seems to go on there. BTW, do you know where the jamming is coming
from? If it's from orbit, being low in CO wouldn't matter too much, but
I suspect it's from ground based emitters.
