I'm currently developing an application in order to make the mavic 2 autonomous in indoor enviroments. In order to do so I need to estimate the location of the drone, so I´m wandering from where does the velocity topic published by the mobile sdk comes from. Is it a fusion between the IMU and the downwards cameras and other sensors or algorithms, or is it obtained from just the IMU?

As I know most of the DJI aircraft data is fusion data

I am trying to work on a project that requires gyroscope data and I was wandering whether it is possible to access this data via the sdk while running DJI Go 4. Thank you very much.

try virtual stick

As kv886 wrote, it's fused from baro, visual, imu ultrasonic.
How the fusing is done only god knows.

The lat/lon start on 0.000 at takeoff, and count from there until you get GPS.

The imu-data isn't available through the MSDK.
It possible to get it, but it's not easily done.

The only easy way is to continously track speed and location and calculate imu-data from there. I don't know if it will be accurate enough since you not saying what you going to use it for.
