Resolution specs. taken during static motions

Accuracy

Pitch: ±0.93 degree typical (yaw from 0 - 360 degrees & roll=0 degrees)

Roll: ±0.33 degree typical (yaw from 0 - 360 degrees & pitch =0 degrees)

Yaw: ±1.0 degrees typical (pitch & roll=0 degrees)

Accuracy is defined as the square root of the sum of the errors squared (non repeatability, temperature coefficients & nonlinearity)

Angle measurement nonlinearity (pitch & roll)

±0.23% F.S.

Angle measurement repeatability

Pitch: 0.07 degrees (typical)

Roll: 0.07 degrees (typical)

Yaw: 0.26 degrees (typical)
