Why high-end drones don't compromise on IMU accuracy?

Attitude control accuracy and system integration have become the key bottlenecks restricting the performance improvement of drones. Drones use the gyroscopes and accelerometers integrated in IMU to achieve real-time measurement of three-dimensional spatial attitude (angular velocity, acceleration) data. The data is transmitted to the flight control system to obtain information such as the attitude, speed, and displacement of the drone. The core of the stable flight of the drone depends on the accuracy and reliability of the IMU.

ER-MIMU-063 MEMS IMU breaks the dilemma of the trade-off between volume and performance of traditional inertial measurement devices. It integrates gyroscopes, accelerometers, and magnetometers internally, providing a solution for drone flight control systems that combines high-precision motion perception with extreme integration.

**Extreme miniaturization and lightweight design**

Using the latest MEMS gyro technology, the size is reduced to 38.6mm×44.8mm×25.5mm, and the weight is ≤70g. The compact structure is easy to integrate into a small payload compartment or flight control system, and is suitable for multiple types of models. Lightweight can directly reduce the fuselage load and optimize endurance.

**High-precision motion sensing performance**

The gyro measurement range is ±400º/s, bias instability < 0.1°/h, and angular random walk <0.05°/√h. In long-duration missions, the gyro output deviation is small, which significantly delays the error accumulation of the inertial navigation system, ensures smooth and stable attitude solution, and reduces the interference of small jitter.

The accelerometer measurement range is ±30g, bias repeatability is 100μg, and the zero bias stability is <50μg, providing a solid foundation for velocity calculation and position integration.

ER-MIMU-063 is a nine-axis IMU that provides real-time feedback of measured data, allowing the drone to perform stable flight, precise hovering, flexible steering and other actions according to instructions. It allows the flight control system to monitor the drone's pitch, roll and heading in real time.

Cost advantage: While ensuring high performance, the price is lower than STIM300. For drone manufacturers and enthusiasts, this means lower production costs and usage thresholds.

**Attitude stability**

When the drone encounters gust interference, the IMU can immediately detect attitude deviation (such as sudden change in roll angle) and transmit the data to the flight control system to drive the motor to adjust the torque and achieve rapid attitude recovery.

When the drone encounters a collision, motor failure or other faults, the IMU can quickly identify the abnormality through the mutation characteristics and trigger the emergency landing procedure.

**Assisted navigation and positioning**

When the drone enters a tunnel, urban canyon or other area with weak GNSS signals, the IMU can provide relatively accurate navigation information in a very short time to avoid flight loss of control.

ER-MIMU-063 has become the "nerve center" of the drone flight control system with its miniaturized, high-precision and high-reliability technical characteristics. It not only meets the drone's aerial photography stabilization needs, but also plays a key role in the autonomous navigation and precision operation of industrial drones.
