Good question wrt the GPS quality. How is a receiver optimized for
aviation?

But I do think the air data makes a huge difference in wind and glide
calculations. Without it, SYM and the SN10 provided varying answers on
the steering to target; with the airdata, they always matched.

I'd be convinced if you disabled the SN10 GPS feed and saw the same
results. Or are you saying the SN-10 is feeding only airdata to the
Oudie and not GPS position data.

PNA GPS receivers are typically optimized for car navigation. *One
result is that they like to say they are going straight even if the
host vehicle is turning. *Ok it's not the GPS receiver itself but the
associated data processing and in some devices, such as the HP310, no
one has yet found a way to hack it so it works properly.

Andy,
do I read you correctly that you are assuming that the Oudie suffers
from the same issue as the HP310? It seem possible that the Oudie was
hacked in such a way as to prevent that, or didn't have the problem in
the first place. It would be interesting to know about that.

I've got two flights on a MiniMap and the wind information is a lot
more believable that what the HP310 was giving me.
