SLC GNSS RECEIVER
NMEA Tab
Setting NMEA Message output
Your surveying, mapping or GIS application is most probably interfacing with the SatLab SLC using the NMEA
message protocol. In addition to GGA message that contains a GNSS coordinate, several additional NMEA
messages offer quality and satellite constellation information. Check your application software regards which
NMEA messages it processes and at what frequency rate, then select accordingly.
Messages are selected/deselected by checking or unchecking the box to the left of the message type. Frequency
is set by clicking on the frequency value next to the message type then selecting as required. Every message can
be sent in intervals of 0.2, 0.5, 1, 2, or 5 Hz.
The above screen shows the setting for Bluetooth but Serial output is also available. Clicking on the ‘Bluetooth’
under the ‘Send using’ heading will open a selection menu with Bluetooth and Cable. If Cable is selected you are
also given the option to select the Baud rate.
Note: You can simultaneously send data via Bluetooth and Serial port with different output
message settings.
