how to provide a autonomous flight to the drone

[Pratikw369]

i am working on UAV with hardware pixhawk 4 and firmware px4 but the issues i am getting is with arming of the drone through mavros
can anyone tell me how to control the drone with ROS2 or how to provide a autonomous flight to the drone (without mission planner)
also i would like to tell that i am not using any gps i am just using single pixhawk (not even remote control)
