I don't really know where this does belong but as this seems to be the closest we have to a "cools military stuff" forum this may be a good read

Happened across vintage Brosnan Bond 'Tomorrow Never Dies' last night in a drunken stupor, within which the very same thing occurs. And that film was made in 1997.
Not suggesting that a Bond film is even close to reality, but if they were thinking about it 20 years ago then I'd be pretty sure such techniques have been in use for some time...

A long way from being rocket science, a HackRF One can do this pretty much off the shelf for £230

It is a fairly basic software defined radio, with a bit of refinement it will easily come in under £100.

That was the first thing that came into my head when I read the title of this thread.Not suggesting that a Bond film is even close to reality, but if they were thinking about it 20 years ago then I'd be pretty sure such techniques have been in use for some time...
Amusing story from my experience a couple of years ago...
I'm an airline pilot based in Hong Kong. One of the things the aircraft navigation system does when you're setting up for the flight is reset it's position using latitude & longitude which we insert (for the inertial systems) which is then cross-checked with the GPS system. Any disagreement will cause an alert.
Anyhow, a couple of years ago, out of the blue, we started getting GPS position disagree alerts when heading past a certain area by the terminal, on the way to the runway. Said disagreement alerts would then clear as we moved on.
Turns out that the airport ground crew vehicles had recently been fitted with GPS trackers to monitor their efficiency as part of a shake-up to improve airport performance.
Not to be out-done, the ground workers just took GPS jammers to work with them. Purchased from the electronic markets in Kowloon. The area where the alerts was occurring was the break area for the guys - so a multitude of jammers was concentrated in a small area.
Good on 'em!
