I think OPB calls out the complexity of gps to cast it's reliability in doubt. But in computers that level of complexity is manageable and not a problem. GPS works.
The problem is it only works when the military says it does. They will turn it off in a heartbeat the moment it becomes a liability to national security. To civilian users the answer will be "tough beans".
