I want to use human's GPS data (I only have GPS sensor)from smartphone to calculate human's velocity, position(utm). How to configure ekf_localization_node and navsat_transform_node?

Yes. It is possible to use robot_localization if we only have GPS. Maybe you can use gps_common package to change the format of gps message and send it to robot_localization. I use smartphone to receive GPS which is already kalman filtered in gps chips. So I have no need to use robot_localization.

And how do you get a world map without robot_localization? I thoght it was necessary.

For my project, I only need relative trajectories of robots. And I can get longitude, latitude, velocity from smartphone using location api. It is enough for me. I don't know what you need for your project.

Thanks for your answers. I want to use robot_localization, but i am a bit lost with tf transforms, but i will figure it out.
