I am trying to figure out the best method in which to handle my task using offboard control and mavros. I basically just need guidance on the mavros portion. I want the drone to begin in a landed state until a GPS lat, long, coordinate target is received. Then it will rise up to 6 feet and move to those coordinates and land there. What is the best way to do this with mavros? Should I use the setpoint_position/global with my GPS coordinates? Is it even possible to takeoff and land as I would like with a python script?
