Live export of telemetry from remote control to PC/laptop

Hello all,

We own a fleet of different DJI drones (Mavic 1 Pro, Mavic 2, Matrice M300, Inspire) as well as different remote controls for them (original + DJI RC Pro).

We would like to transfer the GPS coordinates of the drones live to a PC/laptop via an interface and process them further. Does anyone have any idea if there is a way/special firmware updates/hacks to e.g. connect from the USB interface of remote control/BT/WLAN to PC and stream/save the data?

Of course, another option would be to attach a GPS LTE tracker and track the drone, but usually these parts are sluggish, expensive and unnecessary if the GPS coordinates are accurately transmitted to the remote anyway. The question is – how to export it further to PC in real time.

Additional question – in which unit (drone, remote control, smartphone app) are the distance measurements made? Say, for example, the distance to the drone, what I see on the remote control screen. I imagine that both the drone and the remote control have a GPS sensor and telemetry data is exchanged and distances are calculated, but where exactly does the calculation take place? In that case, if the calculation only takes place in the drone (where the log file is also stored), and remote control only sends its own GPS coordinates, my top question would be completely redundant.

Thanks for your ideas in advance!

Best regards,
Nik

  Hey,

  Interested about this too. 

  With OSDK Expansion module, it was impossible. Tried reading from TX/RX Port, but didnt work. And got confirmation afterwards from DJI, that the data from Expansion module is encrypted :/

  With manifold its probably possible, but it adds quite a bit weight.

  And yes, external GPS seems unnessesary, when there is good gps in the drone.

  Would be interesting to capture coordinates from RC, or the flow of data with wireless. Seems quite hard.

  I suggest you consider the Mobile SDK, you can develop a mobile app to get the telemetry data from the aircraft. You can send those telemetry data to anywhere via the mobile device internet.

  Hi Olli Rinta-Filppula, I highly doubt. You can get Live data feed from the OSDK Expansion Module which would cover few drones such as M300 / M30 isn't it. then why in first place they need to build such Expansion Modules and API?

  Hello Nik Rocky,

  did you actually manage to get this working somehow?

  Interested in the possible solutions.
