In sdk mode flight status gives vx, vy, vz velocities in a fixed frame reference (estimated from downward camera optical flow and other sensors). If you timestamp those data you can get absolute position odometry. But errors accumulate quickly so don't expect to much accuracy after few seconds.
You can get an idea of all this here:
New tool: Tello Vision Telemetry Lab
Telemetry Data Analysis toolkit for the DJI Ryze Tello. Fly the Tello drone with the Tello Vision 1D Android App. Share or Download telemetry data on your PC. Inspect data, view plots, or develop an advanced data fusion algorithm like : - IMU Odometry, - Person Localization Map, - 2D/3D Motion...

is it the vgx, vgy, vgz or the agx, agy, agy? because im trying to get the coordinate data and record it to replay the drones path flightIn sdk mode flight status gives vx, vy, vz velocities in a fixed frame reference (estimated from downward camera optical flow and other sensors).

Tello Localization: Odometry
I made a demo video of Tello localization using odometry. This is position calculation from Tello vgx, vgy velocities provided by Tello state in sdk mode. The analysis shows how quickly the error can accumulate, so odometry alone is unreliable. Algorithm: dead-reckoning from motion model...
