What is a gyroscope used for?

 

A gyroscope is a sensor used to measure angular velocity. Its core function is to sense the rotational motion and attitude changes of an object. It can be applied to various fields that require navigation, positioning or stable control.

ER-MG-057, as a high-performance single-axis MEMS gyroscope (angular velocity sensor), has become an ideal choice for many professional fields due to its excellent performance and reliable design.

Precision instruments and stabilization systems: Ensure precise control and attitude stability of mechanical movement, and improve the real-time and accuracy of target tracking.

UAV/aircraft stabilization: Provides data for the flight control system to sense the attitude changes (pitch, roll, yaw) of the aircraft, so that it can adjust the motor speed to keep the aircraft hovering steadily or flying according to instructions.

Ship/vehicle stabilization system: Large ships use gyro stabilizers to reduce roll; provide reliable attitude data support for autonomous driving.

Robot balance and control: Help robots sense tilt angles and maintain their own balance and motion control.

🛩️ 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

The volume is only 38.6×44.8×25.5mm, and the weight is ≤70g, which can be easily installed in various fuselage spaces.

Compared with STIM300: Double Surpass of Performance and Cost

Excellent Performance: With better performance, the drone can always maintain accurate flight, whether it is surveying, inspection or filming, it can perfectly complete the task.

Strong Stability: Industrial-grade reliability, can work stably in the temperature range of -40℃ to 80℃, baud rate is 230400~921600, supports 400Hz data refresh rate, and real-time feedback without delay.

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.

Indispensable components for DIY drones

 

The cost-effective choice of drone sensors: revealing the secrets of high-performance nine-axis IMU

Sensors are an important part of drones and are the key to drone navigation, stable control and precise flight.

Gyroscopes and accelerometers provide carrier angular velocity and acceleration, which can be used to calculate attitude, speed, displacement and other information. Magnetometers can provide magnetic north direction.

Our IMU ER-MIMU-07 is a nine-axis IMU that integrates these three high-performance sensors. It is small in size and light in weight while ensuring performance, making it very suitable for drones.

**Lower price, higher performance**

Simplify and reduce design costs while maintaining high performance. Lower price than STIM300, but higher performance.

**Attitude control**

Gyroscope measurement range is 400º/s, bias instability is 0.3 º/h. Accelerometer bias stability is 50ug, bias repeatability is 100ug.

It can detect changes in the attitude of the drone in real time, quickly respond to any unreasonable attitude changes, and stabilize the drone.

**Navigation**

Combined with other sensor data, it can help determine the position and direction of the drone for navigation.

The volume is only 38.6x 44.8 x25.5mm, the weight is ≤70g, and the compact and small design can be easily installed on the fuselage of the drone.

**Widely applied**

In addition to drones, it can also be applied to other unmanned systems, such as autonomous driving of unmanned vehicles, unmanned ships USV and underwater vehicles UAV.

The integrated navigation: escorting safe flight of drones

 The integrated navigation: escorting safe flight of drones

GNSS systems (such as GPS, GLONASS, BDS, etc.) provide positioning services with global coverage, but the signals may be blocked or interfered with. They are usually combined with inertial navigation systems to form the integrated navigation system, which can be used in various unmanned systems.

At present, integrated navigation has been widely used in UAVs. It can perform positioning and orientation, and provide attitude, heading and altitude information to the flight control system of the UAV.

The flight control system combines other sensor information to achieve automatic flight, and can also use the combined attitude information to achieve fuselage attitude stability.
