NMEA Record

Description

GGA

Global Positioning System Fix Data.

GSA

GNSS DOP and Active Satellites

GSV

GNSS Satellites in View

RMC

Recommended Minimum Navigation Information

VTG

Course Over Ground and Ground Speed

GLL

Geographic Position – Latitude / Longitude

ZDA

Time & Date

Those messages are output at TX1 at the rate of 4800 bps (default setting). When

more than 4 messaged are chosen, a higher baud rate than 4800 bps is required.

The following will summarize the available NMEA messages. More information about

the NMEA messages refers to “NMEA 0183, Standard For Interfacing Marine
