The RT is able to filter the linear acceleration and the angular acceleration before they
are output. These filters affect the outputs on the CAN bus. On the NCOM output the
non-filtered values are output together with the filter characteristics and the NCOM
decoders provided by OxTS will implement the chosen filter. The linear acceleration and
the angular acceleration can be configured separately.
Due to vibration the accelerations (both linear and angular) are noisy. In particular,
angular acceleration is normally filtered when it is used. The RT can filter the
acceleration outputs using a second order low-pass filter. The characteristics of the filter
can be set and viewed in the Acceleration filtering properties window (Figure 35).
