From flight control to fault diagnosis, how does IMU dominate drones?

For drones. Have you ever been curious: Without a pilot, how does it maintain stable flight and complete various difficult actions?

IMU integrates gyroscopes and accelerometers. The measured data enables the drone to know its attitude, speed and position in real time during flight, and then flexibly adjust the flight status according to preset instructions.

For professionals in drone research and development, application, and production, the selection and correct use of IMU are crucial and directly related to the performance of drones. When selecting, key indicators such as accuracy, stability, and compatibility must be considered.

Take an IMU ER-MIMU-03Mini as an example. It has the characteristics of high accuracy, high stability, small size, light weight, and low power consumption.

From Flight Control To Fault Diagnosis, How Does Imu Dominate Drones

Flight attitude control

The built-in gyroscope measurement range is ±400º/s, bias instability <0.3 º/h, and angle random walk <0.125°/√h. The accelerometer measurement range is ±30g, bias stability <50ug, and bias repeatability of 100ug.

The measured data enables the flight control system to monitor the pitch, roll, and yaw attitude of the drone in real time, and adjust and correct the drone's flight attitude in time.

Navigation and positioning assistance

IMU works in conjunction with GPS and other systems to play a key role in navigation and positioning.

The IMU volume is 40*40*42/27*26*34 (mini version without shell and baseboard), and the weight is 80g/40g (mini version without shell and baseboard). Compact and small design for easy integration.

The unique inner platform design gives it high stability. It adopts modular design and provides OEM customization services.

Simply connect the IMU to the user's system and acquire data without using the 15-pin plug we provide. By removing the bottom plate shell, the size and weight can be greatly reduced.

Fault diagnosis and prediction

The flight parameters of a normally flying drone, such as acceleration and angular velocity, are in a relatively stable dynamic range. Once the IMU detects abnormal fluctuations in these parameters, it may indicate a potential fault.
