-5° for the IMU with respect to reference frame x mounting angle
IMU with respect to Reference Frame
Measure and record the rotations that you must apply, using the Tait-Bryan sequence explained above, to
align your chosen reference frame with the IMU reference frame.
Sensor 1 with respect to Reference Frame
Sensor 1 is typically a multibeam transducer. Measure and record the rotations that you must apply, using
the Tait-Bryan sequence explained above, to align your chosen reference frame with the sensor 1 frame.
Sensor 2 with respect to Reference Frame
Measure and record the rotations that you must apply, using the Tait-Bryan sequence explained above, to
align your chosen reference frame with the sensor 2 frame.
Note
: If your application does not use a second sensor, record these mounting angles as zero.
Installation Checklist
This checklist is included to help you install the POS MV efficiently and with minimal disruption to the
vessel, its crew or any ongoing operations.
After installing the system correctly and all items have been checked against this list, refer to the
Interfaces and Data Formats description starting on page 3-1 to configure and start using the POS MV.
1. Mechanical
Interface
a) IMU
Positioning:
Mount the IMU as close as possible to the multibeam transducer.
Mount the IMU rigidly so that it cannot move or rotate
independently of the vessel.
Install the IMU where the data and power cable will reach easily
between the IMU and the PCS.
Ensure there is sufficient clearance for the connectors at both
ends of the data and power cable. Tighten the connectors by
hand only.
Mount the IMU so that it is approximately level.
Do not immerse the IMU in water or any liquid.
Respect the environmental limits listed for the Inertial
Measurement Unit on page 2-4 for storage and operation.
Refer to the Drawings section on page E-1 for dimensional
details to help when you install the IMU.
Connect the IMU housing to a good ground connection.
