Accuracy <0.5° rms at 0.5 m antenna separation
  <0.1° rms at 2 m antenna separation

 

Pitch and roll angle
Accuracy <1.0° rms at 0.5 m antenna separation

YAW rate
 
YAW rate RMS Noise

0.75 degrees per second**

Definitions

* Circle of Error Probable (CEP): 95 % of the time the position readings will fall within a circle of the stated diameter
 

Note that for comparison, the VBOX YAW02 or IMU rate sensor has an RMS noise of 0.05 degrees per second, so it should be noted that the Slip Angle sensor calculated YAW rate is significantly noisier than a solid state sensor for yaw rate measurement.
