YAW rate
YAW rate RMS Noise0.75 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.
