Good morning I am using the nmea_navsat_driver package via $ rosrun nmea_navsat_driver nmea_serial driver for a gps glonass U-blox7 usb. When I run this package I get a series of topics such as:

/ fix
/ nmeaGPS_height
/ nmeaGPS_latitude
/ nmeaGPS_longitude
/ nmeaGPS_position_covariance_0
/ nmeaGPS_position_covariance_4
/ nmeaGPS_position_covariance_8
/ nmeaGPS_position_covariance_type
/ nmeaGPS_status
/ nmeaGPS_status_service
/ rosout
/ rosout_agg
/ time_reference
/ vel

But I don't get the topic / heading which is what I need for orientation. What is the problem?

Thanks in advance. Regards.

Hello, first of all if you see the corresponding driver.py code, the following appears within the code: "Creates the following ROS publishers: NavSatFix publisher on the 'fix' channel. TwistStamped publisher on the 'vel' channel. QuaternionStamped publisher on the 'heading' channel. TimeReference publisher on the 'time_reference' channel. " You can see a topic called / heading.

On the other hand, what you tell me about robot_localisation can I implement it having only one gps without having IMU?

Thank you. Regards.

If you go through the nmea_navsat_driver you will see that it does not publishes any topic called /heading.

You need to follow these steps to and fuse the data with robot_localisation
