IMU Datasheed?

Posted by Georg on March 18, 2013 at 4:32am

Hey!

I was wondering if there is a datasheet or any Information on the IMU used on the APM2.5? On the ArduPilot page there seems to be only information on the APM1 hardware - and even there I can not find any datasheets or similar information. I would like to know the error covariance (or information concerning the noise and offsets etc) of the gyros and the accelerometers...

In case you are wondering why I am interested in such stuff: I want to implement a kalman filter for my copter :) In the worst case I would need to try out different values until I get a good result.

Thanks for any suggestions!

Georg

    Apologies. I can't get edit to work. Tried 'editing', and it creates a new post. Doesn't seem to want me to post a link to the data sheet, which is what I was trying to add to the post... :(

    It's the Invensense MPU-6000 I think:
