How to use rtk gps with mavros
I bought Here+ RTK GPS with Pixhawk 2.1 Flight Controller. I tested RTK GPS in QGroundcontrol, But I want to flying in offboard mode with mavros.(ex. roslaunch mavros px4.launch) Is there any additional setup needed? or mavros is set up automatically? And which topic should I receive?(global_position/global or global_position/raw/fix or any other topic)
