How To Calibrate The Compass On a Drone?

Every drone pilot is looking forward to his first drone. They want the drone to show cool flying poses and take great, vibrant photos. Drone flight and drone photography have expanded people's lives, but your drone can't take off, and you are prompted on the remote that you need to calibrate the compass, what's going on?

A drone compass is used to provide heading reference and help you get correct navigation. Compass calibration on a drone is done to align the drones’ flight system with the Earth’s magnetic north, not its true north. This phenomena is known as magnetic declination and accounts for the Earth’s shifting magnetic field (typically by a large number of degrees to that of true north). Just as the GPS setting on our mobile phone can help us determine our location, the mobile phone also has a built-in compass to guide us.

Calibrating the compass will keep your drone flying safely.

The Reason You Need To Calibrate Your Drone Every Time!

If you find that your drone compass needs to be calibrated frequently. This may be due to a combination of changing location, changing altitude, interference from metal or strong magnetic objects, firmware update, first flight, SD card incompatibility. This discovery can be frustrating, but calibrating your drone is one of the best ways to keep it safe while flying.

How To Perform Compass Calibration With EVO?

The compass calibration process is needed when flying the Evo drone because it will offset the remote controller and aircraft, if they are not synchronized. Make sure that you have both items powered on and connected to the mobile app before you initiate this calibration.

First, power on the remote controller, aircraft, and connect to the Autel Explorer app to open the settings menu, we can find the compass calibration under the flight status tab.

You can also initiate compass calibration manually without the app connected.

Simultaneously press Takeoff and Landing buttons, followed by pressing Home button for three seconds to start the process. Once it starts, the two LEDs on the rear of the aircraft will turn yellow and flash.

Now hold the aircraft horizontally, point the camera forward, rotate 360 ​​degrees first, until the LED light on the rear of the aircraft turns green and flashes, indicating that the first step has been successfully completed. Now hold the aircraft vertically, with the nose of the drone facing down, and rotate again until the LED light on the rear of the aircraft turns solid green, indicating successful calibration.

If the calibration is successful, you will be notified on the RC display. If the calibration is unsuccessful, the two LEDs on the rear of the aircraft will flash red, if this happens, start the process over again.

How Can I Further Verify That My Drone Compass Has Been Calibrated Successfully?

To check if your drone compass is ready, you can take off your drone and try to yaw about 10 meters off the ground. Check your screen to see if the direction of movement matches the direction the drone is yaw. After calibrating the drone compass, the drone yaw check can further confirm that your drone compass is successfully calibrated.

Drone compass calibration is a maintenance of your drone. If you have performed the above and found that the compass calibration problem persists, you should contact the Autel Robotics after-sales team for support.

Generalize

Smart and advanced drones give us fantastic aerial footage, but for our drones to fly safely, you need to calibrate your drone. Calibrating the drone compass will help the drone pilot to better GPS positioning as well as perform advanced RTH functions, this guarantees that our drone will not get lost easily and you will have a better grasp of everything.
