The Phantom 4 incorporates GPS technology that makes auto take - off, return home,
pre-programmed flight paths, and much more possible.
Several
pre-programmed flight paths allow you to dictate exactly how you want the drone to follow you.
From there, the drone flew to the home based on
a pre-programmed flight path, dropped off the package held inside a small cage, and then flew off to rendezvous back with the van — which had since been driven to a spot miles away.
