Do flight logs exist inside DJI mavic 3 pro?

[charliebicks]

Good afternoon,

I have a Mavic 3 pro, and I very much need the flight logs showing gps location and altitude. My controller has died, and my DJI fly app doesn’t have all the logs (missing most from 2023 and 2024)

Can I use DJI assistant to extract these files?

Many thanks,

Charlie

DAT flight logs are stored on all DJI drones. You won't be able to read them since they cannot be decrypted.

Thanks for the response. Is there a way I can get these logs?

What would you do with them even if you could get them?

Need them to verify location and time for a Guiness world record attempt climbing mountains in South America!

If you have any photos shot with the drone, the metadata incorporated in each image file contains GPS location and altitude data for the drone as well as date and time.
However the altitude data is derived from atmospheric pressure and DJI's algorithm assumes standard temperature and pressure.
Because of this it's accuracy varies by +/- 200 metres with changes in local atmospheric pressure.

Any altitude data that could be in the drone .dat files (that you won't be able to decrypt) would be from the same source and have the same inaccuracy.

Thanks for the response. And thanks for the additional information.

When I shoot a video with the mavic 3 pro I get 3 files, the full video file, the lrf file and the srt file. The basic information that I need is in the srt files. I did however, have my brain turned off and so deleted nearly all the lrf files and srt files back in the day, with not even a spark passing through my head that I might actually need this data.

Thanks

As for altitude measurements, the accuracy isn’t important in this case

Similar data would be included with video files if you had subtitles enabled.

You should be able to get the date and time from the flight log file using DJI Assistant. However, all of the location data is encrypted, so you won't be able to extract any of that data.
