including satellite geometry, system errors in
the data transmission and system errors in the
receiver. A higher figure signifies a greater
positional error. A typical receiver has an accuracy
of between 5 and 15 m. As an example, assuming
a receiver error of 5 m, an HDOP of 2 would
represent an error of approximately 15 m. Please
remember that even a very low HDOP figure is
NO guarantee that your receiver is providing an
accurate position. If in doubt, check the displayed
vessel position in the Chart application against
your actual proximity to a known charted object.
• Estimated Horizontal Position Error (EHPE)
— EHPE is a measure of the estimated error of
a position fix in the horizontal plane. The value
displayed indicates that your position is within a
circle radius of the stated size 50% of the time.
• Fix status — indicates the actual mode the
receiver is reporting:
– Fix — Satellite fix has been acquired.
– No Fix — No satellite fix can be acquired.
– D Fix — A differential beacon fix has been
acquired.
– SD Fix — A differential satellite fix has been
acquired.
• Position — Displays the latitude and longitude
position of your receiver.
• Date / Time — Displays the current date and time
generated by the position fix in UTC format .
• Mode — Identifies wether the receiver is working
in differential mode or non-differential mode.
• Datum — The receiver's datum setting affects
the accuracy of the vessel position information
displayed in the Chart application. In order for your
receiver and MFD to correlate accurately with your
paper charts, they must be using the same datum.
