GNSS (GPS) Settings

The settings for your GNSS (GPS) receiver (internal or external) can be accessed from the Satellites
menu: Homescreen > GNSS pop-over > Satellites > Settings.
Settings displayed are for the GNSS (GPS) receiver currently in use. The name of the GNSS (GPS)
receiver currently being used by the system is displayed in the Fix menu.

GNSS Constellations:

The GPS constellation (USA) is always enabled and cannot be disabled. One other GNSS can be
enabled at the same time as GPS:
The GNSSs available are:
• BeiDou (China)
• Galileo (EU) — Not currently supported.
• GLONASS (Russia)

Differential positioning:

• Enable and disable the use of Differential positioning (SBAS) using the toggle switch. Enabling
differential positioning provides more accurate positioning in regions covered by Satellite Based
Augmentations Systems (SBAS).
• Select Select SBAS to view a list of supported SBASs used for differential positioning. The SBASs
being used can be enabled and disabled using the relevant check boxes

COG / SOG filter

Setting the COG / SOG filter according to the amount of your vessel's oscillation (e.g.: roll, pitch and
yaw) provides more stable COG and SOG values.
