Damn you mean I'm going to have to rethink my missile guidance system ;)

What's it supposed to do if the gps is inaccurate (imprecise?), disabled, or deliberately offset. Deliver the package to the wrong location? Arbitrarily blow up? Get lost, run out of fuel, and then crash?
Or how about having something else to help it find the way? Maybe a reckoning that if it was at A moving so fast in that direction it should be near B, so C should be about so far that way, and any notion that it is somewhere that solidly does not fit that should be ignored. Nah.
