I need a pretty good understanding in order to write a paper about UAVs and the Air Force's reliance (JDAMs) on GPS (and vulnerability as a result?). |
One does not need to destroy a satellite to deny the use of GPS signals. There are such things as localized GPS signal jammers that if PROPERLY utilized it will render the GPS signal unusable. The USAF knows a lot about this and ways to minimize the risks.
