If the goal is to similate navy pilots flying with intermittent GPS, they should add a test mode to their planes receivers rather than jamming which disrupts all planes.
- johncolanduoni 9y agoThey probably don't want to have a facility in their software or hardware that could accidentally (or purposely) be set to disable GPS during normal operation. Even something physical like a switch would make subtle sabotage easier.
- Merad 9y agoEh, such features aren't new or unusual. For example most aircraft have a "master arm" switch that enables firing weapons. Typically they have three settings: off, arm, and simulate (or something comparable).
- hudibras 9y agoWhen I was in the Navy, I participated in similar exercises. Operating in a GPS-denied environment is only one objective we trained on. Identifying that you were being jammed was also key. GPS jamming looks just like the "Huh, we're not locking on any satellites yet, better restart it" that we've all experienced with our car or smartphone. Also, it's likely that there are classified counter-counter-GPS systems or tactics that are being tested or trained on during Red Flag and other similar exercises, but these won't make it into the press.

- handedness 9y agoTesting the jamming is as much a part of the exercise as anything. That, and jamming is not a binary thing. Real-world exercises on something like this yield far better training than simulations, which is what a test mode would be.
- cm2187 9y agoI guess it's the same as IT switching off a data centre to test its resiliency. It's a bit blunt but that's the only way all sort of unsuspected dependencies surface.
