Hi,
thought I'd share my experiences with GPS Averaging (on an HD2 running AmericanAndroid). I did some brief checks with a DGPS on survey.
Not statistically significant, but out of 8 readings the average error was still 4.9 (range 2.7-9.7, stdev 2.2). Normal waypoints logged in Locus were 4.7 (.1-6.9, 2.3). I wouldn't mind if the software didn't claim it was good to between 0 and 0.9.
Also did a very quick check of precision, which you can do without a DGPS, by revisiting points. Even that is off by between 2 and 5 metres.
What are your experiences?
Cheers

My experience is that GPS built into phones suck. Use a bluetooth GPS if you want accuracy ;)
I'm lucky I have a DGPS to play with :-)
This app caught my eye as it's a co-app for Locus with some quite wild claims.
