Chinese Regional Navigation Satellite System
(Beidou) is currently being expanded for global
coverage (COMPASS or Beidou-2) by 2020.
Satellite based augmentation systems
(SBAS)
Satellite based augmentation systems (SBAS) are
systems that are used to compliment existing GNSS
by providing differential corrections that improve a
GNSS’s attributes such as accuracy, availability and
reliability.
The image below shows SBAS regional coverage.

GPS selection
You can use an internal (if available) or external GPS
receiver or GNSS receiver.
• Your multifunction display may feature an internal
GPS or GNSS receiver.
• You can also connect an external receiver using
SeaTalk ng or NMEA 0183.
• Where appropriate use the System Settings menu
to enable or disable the internal receiver.
Enabling or disabling the internal receiver
If your multifunction display features an internal GPS
receiver or GNSS receiver then this can be enabled
and disabled by following the steps below.
With the Homescreen displayed:
1. Select
Set-Up .
2. Select System Settings .
3. To enable the internal receiver, select Internal
GPS so that On is highlighted.
4. To disable the internal receiver, select Internal
GPS so that Off is highlighted.
Enabling and disabling differential satellites
You can choose wether or not your receiver uses
differential data provided by SBAS constellations.
From the GPS Set-up menu: Homescreen > Set-up
> System Settings > GPS Set-up :
1. Select Differential GPS .
Selecting Differential GPS will switch differential
satellite (SBAS) reception On (default) and Off.
Choosing differential satellites
You can select which constellations of SBAS your
receiver will use.
From the GPS Set-up menu: Homescreen > Set-up
> System Settings > GPS Set-up :
1. Select Differential System
The following differential systems are available:
