Surveying the transducer and the navigation sensors
An overall procedure specifying the main tasks is provided. It is not within the scope of
this publication to provide detailed instructions for dimensional surveying. Consult the
installation shipyard and/or a naval architect if you need detailed instructions.
Prerequisites
For accurate ship dimensions you need the detailed vessel drawings.
Context
Determining the relative positions of the sensors and the transducer is important. Sufficient
time and satisfactory work conditions must be given to the survey work. The installation
engineers from Kongsberg Maritime and from our authorized dealers are neither equipped
nor trained to do dimensional surveying.
All measurements must be made after the installation of the transducer and the navigation
sensors.
Procedure
1 Define the vessel coordinate system.
2 Define the location of the origin in the coordinate system. If required, identify the
location with a physical marking.
3 Set out the required coordinate reference points throughout the vessel.
4 Define the vessel’s centre line. If required, identify the line with physical markings.
5 Measure the physical location of the transducer.
6 Measure the physical location of the motion reference unit (MRU).
7 Measure the physical location of the global positioning system (GPS) antenna.
Result
The information provided by the dimensional survey is entered into the MF90 software
as installation parameters.
