Re: Gyro Repeatability, Expected Drift ?

Kevin,

Our gyro is set for a 40hz bandwidth, as I recall, and
it is working absolutey great. If I had a problem I
would borrow a scope and sort it out.

The first thing I would do to improve things would be
to add temperature compensation, and then power supply
voltage compensation, but these improvements do not appear
to be required for our use.

Eugene
