smarter” processing of available signals, or is it a perceived ability resulting from a reduced expectation of accuracy
It??s harder to carry on a conversation, with a jackhammer going in the background. Multi path, environments. Provide this noise. Newer receivers filter out this noise better. And, newer receivers get more satellites, and more signals from those existing satellites. And, some of those signals are stronger too. So, newer receivers in general do better in multi path. And your guess is as good as mine, as to what receiver is going the be the best. One fact remains, in the woods, you are always going to have additional fuzz, of a few hundredths.
Newer receivers are going to be better. But what brand is going to be best, is somewhat guesswork.
I??d recommend several demos.
