This section is used for navigation on water. For traveling
on roadways this function is not necessary. A datum is a
mathematical model of the Earth. Map makers may use
a different model to chart their maps, so position
coordinates will differ from one datum to another. Lines of
latitude and longitude on a map or chart are referenced to
a specific map datum. Every chart has a map datum
reference. The datum for the map you are using can be
found in the legend of the map.
If you are comparing the GPS coordinates to a chart or
other reference, the map datum in the Galileo
™
should be
selected to the same map datum that is listed as the datum
used to generate the chart or other reference. If the datum
setting on the Galileo
™
is different than the chart used, your
coarse could very well be off. This can be dangerous. The
common datum used is WGS84 and this is Galileo’s default
datum and one of 221 datums in memory.
To change the datum
1. Select “Datum” from the main menu.
2. Select the datum that matches the chart you are using.
Tip: When “Datum” is selected, press Menu to choose the
new datum by the beginning letter.
