Slip angle |
|
|---|---|
| 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 |
| <0.25° rms at 2 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.
