It has been said that a russian company has provided Iraq with a system that destroys GPS navagational status of onboard cruise missiles, rendering the missile to be co-ordinless?

As the first of these missiles that have been 'un-guided', how simple is it to actually 'jam' GPS sytems?..is it feasable?

Surely if one has such a system, then it is just as feasable that with todays technology, you could re-programme any 'GUIDED' system, to another co-ordinate, whilst the missil is still in flight? The speed of 're-guidence' systems could be used to send the missile back to where it originated from?

Is this situation possible?

Possible, maybe. But not with the same tech as a jamming device. A J-Dams bomb or missile receives radio signals from sattelites and, if I understand correctly, a jammer floods that radio frequency, so the guidence system is unable to receive. Recieving that signal is quite different from programming a target. To re-task the device to a new target would require reprogramming the targetting computer.

Or maybe it could be done by precisely mimicing the sattelite's signal, and convincing the missile it was at whatever location you tell it.

It's actually quite easy to jam a GPS signal: you just transmit on the same frequency with more power. However, your jamming equipment needs to be fairly powerful to do the job properly -- even more so when GPS III comes out next decade -- and that makes it rather easy to pinpoint whatever's doing the jamming.

It's a fair bet that unlucky person would quickly become a target for lots of non-GPS guided weaponry.

All GPS-guided munitions will fallback to more primitive methods of guidance if they lose the signal. Cruise missiles usually have TV guidance systems; JDAMs and bombs might just go back to inertial guidance (become dumb bombs again).

The military GPS signal is heavily encrypted, so spoofing it is basically impossible.

Maybe not as easy as it would seem - none of the jammers did their job and one was even taken out by a jdam.

Ranyart, it is possible to spoof gps and make it give inaccurate positions (for military gps you need to break the encryption to do that) but to make it give specific inaccurate positions to gain guidance control of a missile would be pretty much impossible.
