patent for bank angle from GPS signals

Some will find this reference interesting. An underlying assumption
for the patent seems to be the airplane is in coordinated flight.
Isn't that an uncomfortable assumption for most of you -- slips along
a straight track would go undetected as banks, wouldn't they?



Apperently current GPS's have a turn and bank indicator on them and they
work OK. But, I would like to see quantifiable data on the effect of
uncorrdinated flight and the effect of winds on this. I am thinking
coordinated flight errors will be smaller than wind errors. It take a HUGE
slip to generate a standard rate turn.
