nmea_gps_driver is a simple NMEA driver. It supports reading NMEA strings from a serial port or topic and outputting the appropriate ROS messages. Currently supported output messages are sensor_msgs/NavSatFix for positional information, geometry_msgs/TwistStamped for velocity information reported by the GPS unit and sensor_msgs/TimeReference to output the current time according to the GPS unit. This driver is meant to be cross-platform and avoid a dependency on GPSd.
For convenience, the major API changes for Hydro are:
- nmea_gps_driver.py is now deprecated and will be removed in I-Turtle. Replacement node is nmea_serial_driver.py .
- Refactored code into NMEA parser, common ROS driver and added separate nodes for reading directly from serial or from topic.
I've created an API review page:
