Answer to: What are the different inertial sensor in the iPad 2 3G?Hi Laurent, Sorry for my late response. Would you need help in implementing a Kalman filter (or higher order filter) for all the available sensors in iPad 2? I'd certainly be interested to help out of interest. Please email me at email@example.com if you are interested. Thanks, Kyle.
Answer to: What are the different inertial sensor in the iPad 2 3G?Hi Laurent, I'm very interested with programming a navigation algorithm using Kalman filter with all available sensors. Apparantly iPad 2 has 3-axis accelerometers, 3-axis gyroscopes and GPS (3G version). I'm currently using Asus Eee Pad, pretty cool, it has quite some apps that can extract sensors data, GPS, 3-axis accelerometers, 3-axis gyroscope, 3-axis magnetometers ... KL.
