FAA Warns of GPS Outages This Month During Mysterious Tests On the West Coast (gizmodo.com)
Long-time Slashdot reader schwit1 shares a Gizmodo report: Starting today, it appears the U.S. military will be testing a device or devices that will potentially jam GPS signals for six hours each day. We say "appears" because officially the tests were announced by the FAA but are centered near the U.S. Navy's largest installation, China Lake, Californi -- home to the Navy's 1.1 million acre Naval Air Weapons Center in the Mojave Desert. And the Navy won't tell us much about what's going on. The FAA issued an advisory warning pilots on Saturday that global positioning systems (GPS) could be unreliable during six different days this month, primarily in the Southwestern United States. On June 7, 9, 21, 23, 28, and 30th the GPS interference testing(PDF) will be taking place between 9:30am and 3:30pm Pacific time. But if you're on the ground, you probably won't notice interference.
3 hours in a checkpoint with my shoes off, my laptop out, and my belt in a plastic tub as i shuffle with my pants now around my ankles into a giant microwave oven only to have boarded a flight where a thick beard or a mathematics equation on a napkin will get me sent to torture prison wasnt enough. Now, the very agency purportedly keeping me safe from the "terrorists" has knocked out the global system used to guide everything from uber to cruise missiles and my flight to Phoenix is now a flight to Scotland.
Good people go to bed earlier.
I gotta say - those Waze Warriors are getting pretty darn serious!

How would you ever notice a 250 nanometer region of interference?
No doubt all of this is in bits and pieces elsewhere. Feel free to mark redundant.
1. The GPS system is owned and operated by the military. Civilians are secondary users. They get to turn it off any time they want, or reduce its accuracy, etc.
2. People already use readily-available GPS jammers, primarily to steal LoJack-equipped cars. Not sure why they're legal to sell, as a device intended solely for disabling a military-owned system, but http://www.thesignaljammer.com...
3. My money is on the military testing its resiliency to deliberate wide-area jamming or attacks on GPS satellites. It's an obvious way to seriously affect the US military without shooting soldiers, so some countries/NGOs might be more willing to do this than, say, blowing up a bus. My money is also on testing during thesummer during the day because pilots can... y'know... look out the window and see where they are. VFR conditions pretty much guaranteed. (yes, yes, at FL180 up you're in class A airspace and always are on instrument rules, but even A380 pilots need to use eyeballs)
4. There are no commercial aircraft that rely ONLY on GPS. VOR and DME are widely used (especially VOR), and pilots are trained to be able to navigate using those methods (evne non-commercial license holders and non-instrument-rating license holders).
5. I'm a pilot. Only private, but I can navigate perfectly well without GPS, and the plane I most commonly rent doesn't even have GPS. And as a pilot, I'm nothing special. If I were flying in that area, I'd do nothing differently whatsoever.
6. I'm not sure what's up with that Embraer. Something to look up tonight.
Everybody gets what the majority deserves.
