What is the purpose of drone_ap_command topic and how is it different from drone

[alizakidd]

I’ve been working on a project which requires following of certain commands processed from camera feed ,I modified the imagepronode.cpp to extract and process the image and commands ,since that node also publishes on the drone_ap_command topic ,I tried publishing on terminal first, however the drone seems unaffected ,but accepts commands properly from drone_command topic as mentioned in the git repository , so I really am confused what the AP means in this context ,any help would be appreciated.
