Configure telemetry settings

GPS parameters

To configure GPS parameters, go to the Configuration > Telemetry > GPS page.
The following descriptions show how to configure a router to accept and forward GPS data using
the web interface and by using CLI commands.
Enable local monitoring
Allows messages from the GPS receiver may be viewed on the Management > Position > GPS
status page. Which messages are displayed is configured via entries in a table.
GPS Module Initialization String
Some GPS receivers may require configuration via an initialization message at start-up in order
to send the appropriate messages in the required format, at the required data rate. Any such
required command string is entered into the text entry box and will be sent to the attached GPS
receiver module when the router initializes the module.
The table described here controls which NMEA messages should be sent from the module. The
default is to enable all messages.
Fix data (GGA)
Displays the fix data in the selected format (2D, 3D or no fix).
Position (GLL)
Displays the Geographic position (Latitude/Longitude) sentence.
Active Satellites (GSA)
Displays the NMEA sentence containing the number of active satellites for calculating the
position.
Satellites in view (GSV)

All other GPS messages
The above messages are the most common and useful NMEA sentences. Many GPS modules
support additional messages. Enabling this setting causes the modules to output any other
supported messages.
