The charm of IMU application in drones

The charm of IMU application in drones

In life, we are often fascinated by various wonderful drone performances, and various applications based on drones are constantly facilitating and enriching our lives. In order to better cooperate with the use of drones, IMU, as a crucial component of drone flight control system, is very important for drones, which is specifically reflected in the following aspects.

1. Flight stability and control

By combining the data of accelerometers and gyroscopes, IMU can calculate the attitude of drones (such as pitch, roll and yaw angle) in real time, thereby helping drones to achieve stable flight.

2. Autonomous hovering and fixed-point flight

IMU is one of the core technologies for realizing autonomous hovering and fixed-point flight of drones. By accurately measuring the attitude and angular velocity of drones, IMU can assist drones to remain stationary at a specified location or perform precise position control.

3. Route planning and navigation

When drones are planning routes, IMU can provide high-precision position and velocity information, and can be used in combination with other navigation systems such as GPS to achieve more accurate dead reckoning navigation. When GPS signals are unavailable or interfered with, IMU can serve as a backup system to ensure that drones can continue to fly safely.

4. Shooting and image stabilization

Drones are often used to take still photos and videos. IMU combined with optical image stabilization (OIS) or electronic image stabilization (EIS) systems can greatly improve shooting quality and reduce blur and instability caused by drone shaking.

5. High-precision positioning and obstacle avoidance

Combined with advanced algorithms and sensors (such as lidar, visual sensors, etc.), IMU can assist drones in achieving high-precision positioning and obstacle avoidance functions, improving the autonomy and safety of drones.

From this point of view, IMU plays a vital role in improving the stability of drones, so the importance of choosing IMU is obvious. What kind of IMU can perfectly adapt to the needs of drones?

ERICCO has a high-performance MEMS IMU-ER-MIMU-M02. When traditional IMUs can only output angular velocity and acceleration information, it has added a three-axis magnetometer and barometer, which means that this IMU can simultaneously output angular velocity, acceleration, magnetic field strength and atmospheric pressure information.The main information of the product is as follows:

Three-axis digital gyroscope:

Dynamic measurement range ±450o/s

Bias instability: 2 o/h (Allen variance)

Angular random walk: 0.08o/√h

Three-axis digital accelerometer:

Dynamic measurement range: 16g

Bias instability: 24μg (Allen variance)

Speed Random Walk: 0.02m/s√h

High reliability: mean time between failures >20000h
