Hello. I am doing some research for a project that pertains to multi-copter drones and their transmitters/receivers. The specific model that I am using is the DJI Phantom 2.0
So basically, I would appreciate some guidance/clarification on how the controller communicates with the drone itself. I know the controller has a transmitter that sends out pulse waves to the drone and the receiver that is installed onboard the drone will read these waves and do what the pilot wants it to do. My question is how do the waves carry this information to the drone? The transmitter and receiver must be functioning on the same frequency, but does it use Frequency Modulation, Amplitude Modulation, or Pulse Modulation? I figured it communicates with FM…
For example, if the pilot uses the controller to make the drone go down and to the left, what do the signal pulses that propagate out to the drone look like?
I know the basics of how a transmitter and receiver work and how each of them must have antennas to operate on the certain frequency. Any advice/knowledge/guidance on HOW the controller communicates with the multi-copter would be much appreciated!
Thank you in advance.
(PS: if anyone has any schematics for the DJI Phantom 2.0 or any similar multi-copter, I would appreciate it! I am assuming that most multi-copters have similar schematics for the controllers and drone body.)
