What is the best approach to calculate the yaw from a 9axis absolute orientation sensor? My math skills from 40 years ago are a little rusty, so I need some help. It helps to think of this problem as determining the yaw of an aircraft from a 9DOF chip riding inside.
• Absolute Orientation (Euler Vector, 100Hz) Three axis orientation data based on a 360° sphere • Absolute Orientation (Quaterion, 100Hz) Four point quaternion output for more accurate data manipulation • Angular Velocity Vector (100Hz) Three axis of 'rotation speed' in rad/s • Acceleration Vector (100Hz) Three axis of acceleration (gravity + linear motion) in m/s^2 • Magnetic Field Strength Vector (20Hz) Three axis of magnetic field sensing in micro Tesla (uT) • Linear Acceleration Vector (100Hz) Three axis of linear acceleration data (acceleration minus gravity) in m/s^2 • Gravity Vector (100Hz) Three axis of gravitational acceleration (minus any movement) in m/s^2 Any ideas on how to best approach this problem will be greatly appreciated.
