GPS Antenna Mounting
It is important to input the exact mounting position of the GPS Antenna on the vessel as this
influences the accuracy of the displayed target in an ECDIS.
(RefPntExt:)
= The position of any external positioning device (GPS Antenna) used as primary
position source.
(RefPntInt:)
= The position of the GPS Antenna (fallback device in case primary source is disabled).
After antenna installation, the distance from the sides must be measured and input.
Either the distance from the vessel’s bow (a) or the stern (b) and starboard (d) and backboard (c) are
required.
e.g. A vessel with the following dimensions:
Length: 100m
Beam:
20m
Input:
A90C5 - then press Enter or
B10D15 - then press Enter
Result:
RefPtExt:
A90 B10 C5 D15m
The NAUTICAST2 automatically calculates the missing distances (a) or (b) and (c) or (d) - based on
the vessel’s length and beam.
Note:
When receiving position data from large vessels, it should be considered that the position refers to
the antenna mounting point upon the vessel. To ensure accurate navigation, the antenna reference
points (see Other Vessels Details) should be taken into consideration when determining the vessels
position.
