Pretend that
1. they jam the control signal and the drone goes into safe mode, tries to return to base.
2. Now, let's also jam the GPS signal with fake information to distort the earth's map so that it thinks that the base is somewhere inside Iran.
3. Show pretty pictures to the press with the intact drone.
I think I saw some movie about this

- StavrosK 15y agoHow are you going to fake the GPS map? It sounds pretty hard to do. Is there an actual attack? I guess you could do it if you had actual atomic clocks sending precisely-calibrated signals made to look like the satellites were wherever you wanted them to be. Still, I guess it would be pretty hard to jam the actual satellites, since you'll also be jamming your own signal.
- ww520 15y agoYou can just jam the GPS signal. The plane when lacking location info and C&C info would just land in wherever it is.
- ppereira 15y agoThat seems like a pretty silly design. Can you imagine if cold war era ICBMs did the same?
- tomsaffell 15y agoIndeed. ICBMs perform a celestial fix in that case.
- slug 15y agoWell, if you ever tried to use a more powerful RF transmitter than your neighbor, you can overwhelm her signal, no need to "jam" with noise or mine for that matter. I should have used a different word than jamming for the GPS map distortion, since it might imply that I was referring to sending random gibberish, so wikipedia to the rescue: https://en.wikipedia.org/wiki/Meaconing https://en.wikipedia.org/wiki/Meaconing Now, knowing that DGPS (https://en.wikipedia.org/wiki/DGPS https://en.wikipedia.org/wiki/DGPS) is pretty common, I don't see where's the difficulty on sending a fake signal in the GHz range, more powerful than the weak one coming from the km high satellites. Considering that some(most?) drones send their return video in the clear, I wouldn't be surprised if the GPS systems end up being not properly engineered to handle this scenario.

- nosequel 15y agoJamming the GPS signal is much different than spoofing 3+ GPS satellites. You can buy a 5 watt Russian GPS jammer for fairly cheap, but spoofing GPS, getting it all right is not available on anything publicly for sale. Pretend Iran could get that math right at the same time as jamming the plane (from above btw!!) to block the real GPS satellites. I'm sure one of the many http://lmgtfy.com/?q=gps+anti-jam http://lmgtfy.com/?q=gps+anti-jam defense contractors would happily sell the military something that might resolve that issue.
