Prerequisites
For accurate location of the global positioning system (GPS) antenna, you need the detailed vessel drawings. For maximum accuracy, we strongly recommend that you use the information provided by a dimensional survey.
NoteDetermining the relative positions and orientations of the sensors and the 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 MS70 software as installation parameters.
Neither tools nor instruments are required. The MS70 is switched on and working in normal operational mode.
Context
The global positioning system (GPS) measures the geographical location of the vessel. On the GPS Offset page, you must define the physical location of the GPS antenna related to the Ship Origin.
The physical location of the global positioning system (GPS) antenna relative to the transducer is required to allow the MS70 to show the correct navigational information in the MS70 presentation.
NoteThe Kongsberg Seapath® - and other GPS systems - offer positioning data that are already compensated for the physical position of the antenna. If this is done, the GPS offset values in the MS70 must be set to 0 (zero) to avoid "dual compensation".
