The IQ of a “smart bomb” goes down without GPS. I talking about ground pounders.
True, but there is whole bunch of people who rely on precise navigational positions...
Aircraft, Ships, Submarines, etc...all need to know exactly where they are in relation to other places....
If the smart bombs are using GPS and the troops are using compasses and maps, there are going to be problems. Everybody should be on the same tech. When the GPS system fails, compasses and maps will be a good backup and the smart bombs and missiles will be offline, anyway.
