Still ridiculous.
You didn't provide
any links (until late). If you don't like the links,
provide better ones rather than blathering incoherently.
I never said this, Talk about moving goal posts!

???? This is just clueless.
Small devices
aren't as good as "survey grade" devices that use D-GPS and WAAS.

They obviously aren't. Hence my point that going to even smaller than the cycling computer is ridiculous. That article which referenced that was from BEFORE GPS WAS UNSCRAMBLED. SInce then, not only is GPS unscrambled, but there are more precise sat navigation systems available, plus better hardware when it comes to handheld devices and smaller.
What is so difficult to understand here? You don't read the articles you post, you don't even realise that you posted an article from before GPS was unscrambled twenty years, you fail to understand your own arguments, and you fail to understand technology.
No one can keep at it and continuously move the goalposts like you do and yet still be considered honest. Especially not when reality has been pointed out to you so many times. You are now on my ignore list.
I forgot, since you still refuse to face facts:
Before GPS was unscrambled (as at the time of writing that USCG article), the precision was "within 100 metres" (330ft) in
ideal conditions. Obviously, that isn't even close enough for good altidude. Since then, not only has GPS gotten better, there are more precise sat systems available, AND the receivers of today - regardless of size - receives the signal from many more sats than they did in 2000 and before.
