The MRU 5
The Seatex MRU 5 is specifically
designed for motion measurements in
marine applications. The unit incorporates
3-axis sensors for linear acceleration and
angular rate, along with complete signal
processing electronics and power supply.
The MRU 5 outputs absolute roll and
pitch. Dynamic acceleration in the MRU
axes direction as well as velocity and
relative position, are also provided. The
MRU achieves high reliability by using
sensors with no rotational or mechanical
wear out parts.
Figure 7 The MRU 5
When the MRU is used within the Seapath product, only raw angular rate and linear
acceleration data is output from the unit. All processing of these signals to roll, pitch,
heave and velocity measurements is performed in the Kalman filter in the Processing
Unit. The analog output channels from the MRU, as indicated in Figure 8, are therefore
not used when the MRU is used within the Seapath product.
