Package and Setup​

The Novatel Smart7 GNSS antenna uses the nmea_navsat_driver ROS 2 driver. The driver is open source, maintained by the community, and hosted on GitHub.

For specifics on the way Clearpath's configuration system launches the sensor driver, see the Navsat Smart7 launch file and the default parameter file in clearpath_sensors.

Device Path​

The port ROS parameter must be set to the device path of the Novatel Smart7. To simplify this process, use the /dev/clearpath/gps path. This path is only available when the Clearpath robot UDEV rules are installed. These are installed alongside the clearpath_robot package. If the receiver is connected, but the /dev/clearpath/gps device is not, check the file /lib/udev/rules.d/60-ros-jazzy-clearpath-robot.rules exists.
