I am looking for a drone which is able to:
- maintain an RF link between 5-10km from the receiver
- get easily modified to carry an external payload (assume another IMU+GPS) and transmit the payload data to be retrieved on ground by some kind of UART interface (~10-20kbps)
- has small definition video just for FP navigation
No particular agility or battery life requirement.
I am able to implement this sort of systems, but since this is a test setup for something which will require much more effort to develop, I am looking for the quickest way to do that and I have no experience with drones.
Any recommendations are welcome, given the sea of available choices.
I guess the underlying question boils down to which drone is hackable the easiest.
I have looked around and could not find any which had a clear path to handle an external payload as part of the system, especially for these kind of ranges.
Edit: Apparently the DJI Mavic etc. have Transparent Data Transmission, which looks like it allows us to interface with one of the onboard UARTs for up to 4kB/s which should be enough. But the data is only retrieved on Android - isn't there a more direct way to obtain the data on a Linux PC?
