How to implement remote control of a quadcopter?

Question

Do it yourself

I have Mavic Pro and Mavic 2 Pro quadcopters. They are controlled directly from the remote control + smartphone (without a smartphone it does not fly further than 25 meters), at a distance of 6 km of line of sight. The filming location is 40 km from the office, filming is done for 25 minutes, every day.
How to automate the shooting process without the participation of the operator. The copter will be charged, turned on and set to the takeoff position, but no one will control it except me. Is it possible to control the takeoff, flight, landing of a quadcopter and uploading video from it directly via the mobile Internet?

Answer 1

Leave androy smart there with a team weaver or vns?))
Although these are such crutches))
Mavik also has a closed firmware ...

Answer 2

Once, at one hackathon, people dismantled the remote control of the drone, soldered wires there, screwed the controller and began to send commands there, as if you were standing and pushing the levers-buttons on the remote control. It is solved purely at the level of circuitry, no proprietary protocols need to be hacked.
closed the contacts - the button was pressed.
True, they controlled it with the help of leap and passes with their hands in the air, but this is for showiness. You can simply solder the same wires to the second remote control at home and send clicks from your lever buttons.
I won’t say anything about remote connection to a smartphone, but everything is possible on android, this is the least of the problems.

Answer 3

If the weather is calm for 40 km, there are no high-voltage power lines, then it is possible to build an RPA drone on the basis of an existing quadric, equipping it with a web camera. It will take off from the same point to a given height and follow the same route specified in advance (without GPS), return to the same point and switch to the state you need. The route for learning the system must be passed 1 time in the remote control mode by manual control.
