Stay tuned! Somehow, I find it difficult to believe I'm dignifying this with a response (much less a public one), but here goes: Every commercial GPS unit that I have ever seen has a speed which, if exceeded, will cause the unit to shut down (usually until power-cycled). It varies from unit to unit, but in every observed case was substantially (several times) less than the speed of such weaponry in flight. Commercial units also have altitude limits, with the same consequences for exceeding them. Integrating an OEM GPS module with existing avionics systems' targeting mechanism so it can actually cause the missile to adjust its course is left as an exercise to the local defense systems integrator.
