Ardu IMU and drift

Posted by Phil G on March 11, 2010 at 10:12am
Hi,The ArduIMU seems to be a very good product and I have a small question about it.What kind of drift can be expected of it if the IMU is used in a slow and vibration free ( 0-20 kmh) vehicle after some time?For example, after 5 minutes? 20? 60?ThanksPhil

    "We are not using high end gyros…"

    What kind of characteristics should we look for if we wanted high end gyros?

    Sounds dumb, but I'm quite the electronics newbie.

    Zero. That's the whole point of an AHRS (which is the plus in ArduIMU+): it fuses data from the accelerometers and gyros and GPS to converge on the correct attitude at all times.
