Slip angle
Accuracy <0.5° rms at 0.5m antenna separation
  <0.1° rms at 2m antenna separation
Pitch and roll angle
Accuracy <1.0° rms at 0.5m antenna separation
  <0.25° rms at 2m antenna separation
YAW rate
YAW rate RMS Noise

0.75 degrees per second**

Definitions      

* CEP = Circle of Error Probable

  95% CEP (Circle Error Probable) means 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.
