1986

I'm sorry, but I fail to see how that relates to anything I wrote in
the article to which you are following up.

There a post about the age of GPS, I just pointed out that
it was commercially available and used in 1986. Our news
servers had some problems, your post was what I had visible.
I don't recall seeing any thing I wrote that should have
insulted you.

Ah, I see. And your point is that GPS has been around a long time,
and you have heard no mention of anomalous behavior due to solar
storms. But if you look at the information in some of the links I
posted, you'll find that those who are intimately involved with GPS
operations have observed significant errors in various locations as a
result of changes in the ionosphere such as convective plasma
currents, etc.

I wasn't insulted; confused.

But a properly trained pilot and his passengers are
dependent on a perfect GPS, VOR or Lycoming engine.
