No, I didn't post a link that was wrong in any way. I was not the tosser who posted the link with the Survery grade info in it (the USCG article). You posted that.
To explain in easy terms I made a comparison to using a hand-bearing compass. Hence I used the terms you use when use a hand bearing compass. It made everything simpler. Yet you still failed to grasp the simple concept.
And, yes,
Garmin rates
their own products as using the best technology ever. What a surprise. It wouldn't actually sell units using cheap hardware if it said they used old and cheap technology to improve their margins, now would it.
As for your selective availability comment. You are talking about the unscrambling of the GPS signal. Don't pretend it is something else and as if it was something you knew. Don't pretend you actually know something, because it is obvious you know absolutely nothing about GPS:

And ten years after (2010):

It is obvious you looked it up, then looked for something that would somehow disprove that it was unscrambled in the year 2000. It's another word for the
implementation of scrambling of the GPS signal so only military units could use the higher precision signal.
Let me repeat: At the time of writing that article you posted as "evidence", the best precision GPS could muster was
100 metres in ideal conditions. The reason was that the signal was scrambled so non-military units couldn't use it precisely enough for nefarious reasons.
Another titbit of information you will continue to ignore is that the reason the US military stopped the scrambling of the signal was that technology had caught up to it, so scrambling it was pointless. Hence Clinton signing an order in
May 2000 to stop the scrambling of the GPS signal.
But you're right I kept coming back to your posts, because I hadn't also unsubscribed. That was idiotic of me. Now I will both have unsubscribed as well as having you and your posts on ignore.
