Tello Pad Location Values Variation

[Javaid_kfupm]

Dear community,

I am trying to track the tello drone location through recording x, y, and z values received from the drone with the following commands:
get_mission_pad_distance_x()
get_mission_pad_distance_y()
get_mission_pad_distance_z()

However, when I plotted the x, y, z for the straight line movement of the drone, I noticed variation in the location values. the value jumps to big value and then comeback. I was wondering why this happens.

I attached the plot of x and y for straight line movement. The drone moved straight line but the values of x and y are not straight line, why?

There are clearly two straight line sections, moving away from the pad. Maybe you didn't narrowed the data to correct time slice?
