The available NMEA message types are:
Details of all the available NMEA message types are available in Section 4.
It is recommended to enable only the messages which the receiving vessel system
requires.
2.6.2.4 NMEA Config
This menu allows the user to configure some of the characteristics of the GGA message.
The two available options are Precision and PPP DQI.
Precision
The number of decimal places in the latitude and longitude fields of the GGA message.
Values between 5 and 8 can be selected. Default is 5.
PPP DQI
The default PPP DQI value is 2. This option relates to the output of Apex or Ultra (PPP)
solutions. PPP solutions offer a higher positional accuracy compared to single frequency
DGNSS (e.g. VERIPOS Standard).
One of the fields in the GGA string is the solution DQI (Differential Quality Indicator).
If the PPP DQI setting is set to 2 on this page, the DQI value in the GGA output will be 2 for
all corrected solutions.
If the PPP DQI setting is set to 5 on this page, the DQI value in the GGA output will be 2 for
all Differential solutions (e.g. VERIPOS Standard, 3

Party) but will be 5 for PPP solutions.
