Prerequisites
For accurate location of the global positioning system (GPS) antenna, you need the detailed vessel drawings. Neither tools nor instruments are required. The ME70 system is turned on and operates normally.
NoteDetermining the relative positions and orientations of the sensors and each transducer with high accuracy is important. This requires professional land surveying done by qualified and trained surveyors using proven survey equipment and methods. We recommend that you use third-party consultants with well proven experience with vessel dimensional control. The information provided by the dimensional survey is entered into the ME70 software as installation parameters.
Context
The physical location of the global positioning system (GPS) antenna relative to the transducer is required to allow the ME70 to show the correct navigational information in the ME70 presentation. The locations of the transducer and the Global Positioning System (GPS) antenna must be referenced to a common Ship Origin.
NoteThe physical location of this sensor was specified when the communication parameters were defined. If this was done correctly, it is not necessary to do it one more time.
