The number of satellites visible can be seen in the GPS Info (second method call, above).\n\n\u003e Note, it may take a few moments for the dongle to reboot the first time.  This REDHAWK Device issues a cold start message to the dongle in an effort to ensure it does boot to a good state ready to output NMEA strings.\n\nAt this point once you've verified the device can read from your interface, issue `gps.stop()` and exit the python shell.  Then feel free to `make install` the Device to the Target SDR for integration in a node.\n\n## Usage\n\nThe REDHAWK Device implements the Frontend GPS IDL and only has one controllable property, `serial_port`, for accessing the serial stream.  The default is `/dev/ttyUSB0`.  Ensure the user account that will be running the node executing this device has readwrite access to this location. \n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgeontech%2Fbu353s4","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgeontech%2Fbu353s4","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgeontech%2Fbu353s4/lists"}
