Re: Another Navy ship collision. 10 "missing"
That is my point. If the military version of GPS was distorted, which at least according to the article seemed to be comparatively easy to do, the Navy ships would see the positions of private vessels accurately since they would be on non-military GPS signals, but the naval ship would not see their position accurately because their GPS signal is not the same as the ships around them.
Jeff, it is not any new situation (2 GPS versions used) and the civilian GPS system is not distorted on purpose. It is merely not as accurate but the accuracy is in the range of 10' max. If you get within 20' of another vessel on purpose, you better have physical eye contact with it as well. And no, night is not an excuse for poor lookout. These folks have awesome night vision technology. Navy knows all these were clearly human error situations on their end - as the disciplinary pattern shows. Mind boggling human error situations.
Be kind, for everyone you meet is fighting a hard battle.
