GPS Jamming

Article below talks about GPS jamming during USAF combat training exercises this coming week. It will be interesting to hear of the civilian impact, like geocaching or even car navigation. I wonder if having a device with GLONASS would help or if they will jam all the frequencies.

While heading NW on Nevada 375 6 years ago.  About 50 miles east of Rachel, NV we had 4 GPS'rs "go dark" and they stayed dark until 5 miles east of Warm Springs, NV.  The units included 1 Garmin Nuvi and three Garmin 62s. Considering where we were; we expected the unexpected and were not disappointed. Spooky to say the least.

Sounds like NOTAMs are being issued as a precautionary measure, and that the increased air traffic may be more of an issue than the actual GPS jamming.

The hours are 0400Z to 0700Z, which would be 9 PM to midnight local time.  Might affect some late night ET Highway runs, in theory.  I would be surprised of an actual effect on GPS signal outside of the Test Range, as that could open the Air Force to liability if something goes awry.

I've actually turned GLONASS off, as it was causing oddities with my Montana.  Either way, it's unlikely that the Air Force would only be jamming part of the GPS spectrum if they really want to be testing how GPS denial will play out in this exercise.  After all, why would you only want to jam signals from USAF GPS birds if the enemy might have GLONASS-only systems?
