I find that WAAS isn't as good as local DGPS from the USCG used to be,
even with a clear sky view.  But I have no hard data.

I am headed to corrections over the internet to get more accurate
real-time positions via navigation solutions, so I can map in the field,
and also later.  I would be very happy with 2m accuracy.

I have the impression PPP requires static observations for a longish
time, vs being able to produce a gpx of a moving receiver.

I would like to get RTK working, but my impression is that one needs
unobstructed views and good signals, unless you get recent high-end
equipment.
