Robot Localisation navsat transform produces zero values for odometry/gps
I used the ZED camera to generate a visual odometry message. While collecting the ROS bag, I forgot to set a param in ZED that turns off publishing the odom -> base_link transform. However while collecting the ROS bag, I didn't collect the /tf or tf/static topic at all. Yet, the navsat transform node publishes zero values for odometry/gps. I already have launch a all necessary transforms (imu, GPS and ZED cam in a urdf file) so that does not seem to be the issue.
Could you give more information submitting the launch file of navsat transform node and any configuration file you are using?
