Quite possible. This countermeasure was discussed more than ten years ago. It is possible to turn of the civilian signals -- or to leave then on but _jam_ them within a selected area -- without interfering with US military use of the satellites. A modern military does not need the C/ A code to acquire lock on a satellite. It can acquire the encrypted P code directly." -John ================= > I do not believe that is the case as the terminals I work on, used mostly > by > the Army & the Marines, use relatively cheap GPSs in them and we have them > all over, Iraq, Afghanistan, Kuwait, etc.. 73 - Mike > > Mike B.
