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).
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.
Also, the electronic chart display in use should be programmed to consider the antenna
reference points. Traffic images are represented in true distances only when all displayed
targets, including own vessel, are working with AIS position information, which considers
antenna reference points.
