Thanks for that news Dan. We have archived that note in case it goes missing.
The GPS system, does however remain a system controlled by the military, so it can still do whatever it might deem needed at any time, such as simply shutting it off completely... or blocking certain areas. GPS is also a system that can be jammed from the surface locally without extremely high technology, so as mariners planning on a life that is independent of government resources, we should still look to celestial navigation as the one and only dependable worldwide navigation system.
