🛩️ The "Heart" of UAV Performance - Why IMU is Important?

 

For drones, precise attitude control, stable flight performance, and real-time dynamic response capabilities are key. The core of drones relies on the accuracy and reliability of the inertial measurement unit (IMU).

Take a nine-axis IMU ER-MIMU-07 as an example for analysis. It has a built-in three-axis gyroscope, three-axis accelerometer, and three-axis magnetometer. Combining excellent performance and ultimate cost-effectiveness, it is the first choice for drones. The measurement data is transmitted to the flight control system to obtain information such as the attitude, speed, and displacement of the drone.

Wind-resistant flight and aerial photography

The built-in gyroscope has a measurement range of ±400º/s, bias instability <0.1 º/h, and angle random walk <0.05°/√h. The accelerometer has a measurement range of ±30g, bias stability <50ug, and bias repeatability of 100ug.

The real-time feedback of the data measured by the IMU allows the drone to perform stable flight, precise hovering, flexible steering and other actions according to the instructions. The flight control system can monitor the pitch, roll and heading of the drone in real time.

Lightweight design releases the potential of drones

For drones, the choice of IMU is related to drone performance. Indicators such as accuracy, stability, and compatibility are all very critical. As the “nerve center” of drones, how does IMU enable flight?

Take a nine-axis IMU ER-MIMU-07 as an example, which has a built-in three-axis gyroscope, three-axis accelerometer, and three-axis magnetometer. The measurement data is transmitted to the flight control system to obtain information such as the attitude, speed, and displacement of the drone.

The data provided by the IMU can monitor the pitch, roll, and yaw attitude of the drone in real time. When the drone encounters strong winds or sharp turns, the real-time data of the IMU will trigger the flight control to quickly adjust the motor speed. Ensure stable flight and silky smooth shooting without shaking.

**Small and lightweight: flexible installation**

This IMU is only 38.6x 44.8 x25.5mm in size and weighs ≤70g, so it can be easily installed in various fuselage spaces.
