USAF Is Jamming GPS In The Western U.S. For Largest Ever Red Flag Air War Exercise

The use of the mysterious jamming technology will impact the navigation of aircraft operating as far away from Nevada as Colorado.

The year's first iteration of the USAF's premier set of aerial war games, known commonly as Red Flag, is kicking off today at Nellis Air Force Base just outside of Las Vegas, but this exercise will be different than any in the past. Not only is it the largest of its kindin theexercise's 42year history, but the USAF is going to blackout GPS over the sprawling Nevada Test and Training Range to challenge aircrews and their weaponry under realistic fighting conditions. The tactic will spill over throughout the region, with warnings being posted stating inconsistent GPS service could be experienced by aircrews flying throughout the western United States.

The disruptions will begin on January 26th and will run through February 16th. Flying.com reports:

"The NBAA Command Center reports the U.S. military will begin training exercises on the Nevada Test and Training Range between 0400Z until 0700Z daily. Training maneuvers will impact vast portions of the Western U.S. including California, Nevada,Oregon, Wyoming, Arizona, Utah, Colorado,Montana and New Mexico. FAA enroute ATC centers affected include Albuquerque (ZAB), Denver (ZDV), Los Angeles (ZLA), Salt Lake (ZLC), Oakland (ZOA) and Seattle (ZSE). Operations in R-2508 and R-2501 may also be impacted.

Arrivals and departures from airports within the Las Vegas area may be issued non-Rnav re-routes with the possibility of increased traffic disruption nearLAS requiring airborne re-routes to the south and east of the affected area. Aircraft operatingin Los Angeles (ZLA) center airspace may experience navigational disruption, including suspension of Descend-via and Climb-via procedures. Non-Rnav SIDs and STARs may be issued within ZLA airspace in the event of increased navigational disruption. Crews should expect the possibility of airborne mile-in-trail and departure mile-in-trail traffic management initiatives."

It’s amazing just how much airspace the US military controls.

How much coastline will be impacted by this.

And what about Joe's GPS van navigation - will dogs go ungroomed?

The clued up pilots could well use Galileo https://www.gsa.europa.eu/european-gnss/galileo/galileo-european-global-satellite-based-navigation-system

Or Glonass. You might already be using it.

This is nothing new. It happens at other locations from time to time.

I think most aircraft with modern Flight management and guidance systems using interial reference systems also have back up methods to assure accuracy. The airbus will us gps for position first, if gps is unavailable, it will use radio updating. It will auto tune vhf based navaids from an onboard data base and use distance measuring to fix position. This method is nearly as accurate as gps. All the crew has to do is check the actual accuracy is better than required accuracy.

My guess is all satalite based navigation will be jammed, otherwise, what’s the point. The link says they are all compatible with each other, I believe they will all be jammed.

On the Jurassic jet we’d never know. ;)

Losing GPS is not so good in other places, like the Atlantic Tracks, now that the spacing has been reduced. If an event occurred on that route, it would be a good day to book-off.

The inertial systems are good, but develop considerable error over 6 hours or so.

What about GPS approaches in areas on the outskirts of that Nevada shutdown? Lots of places are moving away from ground-based transmitters, as we know.

I'd be cross-referencing like crazy, and have a really good alternate.

Fake news! It's a way to cover up the arrival of the extraterrestrial delegation, for a meeting with Trump.

our ops specs stipulate that if the destination has gps approaches only, then the alternate must have ground based navaids working.

Love it.

Ive got this one.
