In order for your GPS receiver and multifunction display to correlate
accurately with your paper charts, they must be using the same
datum.
The default datum for your multifunction display is WGS1984. If
this is not the datum used by your paper charts, you can change
the datum for your multifunction display, using the
MENU > Chart
Setup > Datum
menu item.
When you change the datum for your multifunction display, the
chart grid will subsequently move according to the new datum, and
the latitude/longitude of the cartographic features will also change
accordingly. Your multifunction display will attempt to set up any
GPS receiver to the new datum, as follows:
• If you have a Raymarine GPS receiver using SeaTalk or
SeaTalk
ng
, it will automatically correlate each time you change the
datum on the multifunction display.
• If you have a Raymarine GPS receiver using NMEA0183, or a
third-party GPS receiver, you must correlate it separately.
It may be possible to use your multifunction display to correlate an
NMEA0183 GPS receiver. Go to
MENU > GPS Status
. If the datum
version is displayed, it may be possible to change it by selecting the
OTHER SETUP
softkey and choosing the appropriate datum. If the
NMEA0183 GPS receiver does NOT state which datum it is using,
you must select the NMEA0183 GPS datum using the
MENU > GPS
Status > Other Setup > NMEA0183 GPS Datum
menu item.
Note:
Raymarine recommends that you check the displayed
vessel position in the chart application against your actual
proximity to a known charted object. A typical GPS has an
accuracy of between 5 and 15 m.
