Tracker500/500i User Manual

15.0 Chart Datums

GPS derived positions are based on a worldwide reference (datum) known as WGS 1984.
Many charts are based on datums other than WGS 1984. This results in an offset between
a Lat/Lon plotted on the chart and the same Lat/Lon plotted on the Tracker500/500i. To
match the Tracker500/500i with your chart you must enter the datum specified on the chart.
See section 14.0 Setup for details on how to select a chart datum. Once your local datum
has been entered, all latitudes and longitudes, including waypoints, will match the chart.

Note: When using a number of charts with different datums it is important
to ensure that you change the datum to match the chart currently being
used. If the destination waypoint is on a different chart, be sure to
change to that chart’s datum before entering the latitude and longitude of
the destination waypoint.

Alternatively, you can manually enter a lat/lon offset value to bring the displayed lat/lon
values in line with the chart you are using. See the Setup screen for details on how to enter
a lat/lon offset.

 

The lat/lon offset function is typically used to match the Tracker500/500i

with older charts where an island may have a large position error, but all points around the
island have the same error.
