I think that you are going to have to work with TAS instead of GS, but
Figure 2.29 on page 179 of Aerodynamics for Naval Aviators has a graph
of all the factors involved.

Yeah, to be perfectly accurate, I would need air speed and not ground
speed in addition to wind angle corrections, but I was curious if I could
get a good approximation of the bank angle from just what I'm getting from
the GPS without having to add a considerably costlier device like an
accelerometer / gyro with rs232 outputs... The Garmin 18 5Hz puck type GPS
goes for around $150... A bit more than the 1Hz units that are typical for
car navigation, but not entirely out of line for this project... The
accelerometer / gyro systems that I've seen so far with rs232 outputs go
for around $1K-$2K... I understand that there is some new work in
accelerometers for PC-based pointing devices that have brought the prices
down considerably compared to the previous devices like this:
