I'm interested because I know lots of shipping uses GPS satelites now so what would happen to all the civilians if this theoretical GPS encryption was used? |
there is a automatic corruption to all non US miltary GPS units. military GPS is literally pinpoint accurate (depending on the number of satilites it can "fix" onto)
where as civilian ones are acuurate to around 10 meters (or feet)
