DJI Mini 5 Pro - IMU Calibration

Let's start with the IMU, inertia

movement unit. The IMU affects the

behavior of the aircraft in flight. It

is therefore important for the safety of

your unit.

It uses several components of the

aircrafts such as the gyroscope,

barometer, and accelerometer to keep the

drone flying smoothly, stably, and

balanced.

I calibrate the IMU whenever the drone

exhibits unexpected flight behavior.

If the aircraft cannot fly in a straight

line, doesn't maintain the altitude,

drift while hovering, or doesn't respond

appropriately to the sticks of the

remote control. The first thing to do is

to calibrate the MU.

Another occasion for calibration is when

DJI Fly app prompts to do so with an

on-screen message.

The calibration is also suggested after

traveling more than 50 miles, after big

elevation changes, for example, during

the trip to the mountains or when the

temperature is drastically different

from usual.

A few time while traveling I had

experienced a wild behavior of the

aircraft and indeed calibrating the mu

fixed the issue.

For the calibration choose an area far

from metal and free for interference.

Place the Mini 5 Pro on a horizontal

level and perfectly flat surface.

Make sure to have at least 50% battery

time for both the drone and remote

controller.

In the safety table settings, we scroll

down until we find IMU normal and hit

calibrate.

We are presented with a screen that

guide us through the steps needed for

the calibration. We are asked to

position the drone with folded wings in

five different positions.

We start with the drone positioned

laterally with the camera facing to the

left and we can then hit the start

button.

To the right of the screen, a ring shows

the progress of the first step. The

second position is sitting on the left

side of the aircraft with the power

switch facing us and the camera to the

left.

Position three with the drone on its

back and the camera facing to the right.

Position four with aircraft on its right

side and the camera facing to the right.

Position five with the drone standing on

the back showing us the right side.

Finally, we place the drone in the first

position and the aircraft will restart.

It is a bit like doing yoga. The short

video shows these different position. It

should help to get them correctly.

At the end, a message will confirm the

outcome. If the calibration has failed,

move the drone to a different location

far from metal and magnetic

interference.

Make sure that the surface is perfectly

flat and try again.
