GPS Status
Products with an internal GPS receiver or GNSS
(GPS/GLONASS) receiver can use the GPS status
page to view the status of the available satellites that
are compatible with your receiver.
The satellite constellations are used to position your
boat in the Chart application. You can set up your
receiver and check its status from the
GPS Set-up
menu. For each satellite, the screen provides the
following information:

3. Position and fix information
Sky view
Sky view is a visual representation that shows
the position of navigation satellites and their type.
Satellite types are:
• Circle — A circle identifies a satellite from the
GPS constellation.
• Square — A square identifies an (SBAS)
differential satellite.
• Diamond — A diamond identifies a satellite from
the GLONASS constellation.
Satellite status area
The Satellite status area displays the following
information about each satellite:
• Type — Identifies which constellation the satellite
belongs to.
• ID — Displays the satellites identification number.
• CNO (Carrier-to-noise ratio) — Displays the signal
strength of each satellite shown in the Sky view:
– Grey = searching for satellite
– Green = satellite in use
– Orange = tracking satellite
• Azimuth and Elevation — Provides the angle of
elevation and azimuth between the location of the
receiver and the satellite.
Position and fix information
The following positional and fix information is
provided:
• Horizontal Dilution of Precision (HDOP)
— HDOP is a measure of satellite navigation
accuracy, calculated from a number of factors
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
