I am making for my final year project a quad-copter that will detect an object at a specific longitude and latitude. I am using raspberry pi for image processing and pixhawk for the control.
As you know the the GPS is not accurate enough and it might give an error of 1 + meters. For that, the logic behind the project is to let the quad-copter go first to the predefined lon/lat of the object then try to find the target.
My question is the following: I know that I can interface the raspberry pi and pixhawk using Mavlink. But is there any command in Mavlink that allows the raspberry pi to send a move left command for x meters...to the pixhawk?
