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?
