Why does the Slip Angle accuracy depend on speed?
The problem with specifying the accuracy of slip angle is due to the accuracy of velocity. Unless the accuracy of the sensor becomes better as you go slower, the accuracy of Slip Angle for all sensors depends on speed. This effect does not only apply to the RT3000, it applies to Optical Slip Angle sensors too. On the RT3000 the velocity accuracy is the same, regardless of speed. This means that, if you are going slowly then the “track” angle is less accurate. At high speeds the track angle is more accurate. The slip angle depends on the “heading” and the “track” angle. As you get faster the “track” angle becomes more accurate. So the slip angle becomes more accurate too. The fact that the track angle becomes more accurate as speed increases is obvious if you look at it the other way round. As a vehicle gets slower, the slip angle becomes less accurate. As the vehicle approaches zero speed, the slip angle continues to get less accurate until it is no valid. Having no speed (and no valid
