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,

I've been told, and I hope it's correct, that sending a GPS signal to
the 310 will give better results. I will be using a Powerflarm to send
the 310 data and by-pass the internal GPS. It is a simple setting in
the LK8000 software for a com port and baud rate setting.
