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.

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.

Choose a suitable IMU to make your drone flight more stable and safe

 

       As one of the core components of drones, IMU plays an irreplaceable role. Its high precision, fast response and freedom from external interference enable drones to maintain stable and precise flight and accurate navigation and positioning in complex environments, and can also perform fault diagnosis for drones. ERICCO's MEMS IMU can achieve high performance while being small in size and light in weight, making it very suitable for drones.

We have a tactical-grade IMU ER-MIMU-M02, which is low-cost and has an advantage in price. It is a 10-axis IMU with an added three-axis magnetometer and barometer (altimeter). It is only 47×44×14mm in size and weighs 50g. Compared with other IMUs, it is more suitable for drones.

The built-in accelerometer of the IMU cannot be used to detect absolute heading (yaw). The magnetometer in this IMU measures the magnetic field strength in three dimensions, which can help determine the heading of the object as well as roll and pitch, and correct the integrated error of the yaw gyroscope in the sensor fusion algorithm.

The barometer measures the atmospheric pressure and calculates the altitude of the drone, which is crucial for the safe flight of the drone!

The dynamic measurement range of the built-in gyroscope is ±450º/s, the bias instability is 2 º/h, and the angular random walk is 0.08º/√h. The dynamic measurement range of the accelerometer is 16g, the bias stability is 0.1mg (Allen variance), and the angular random walk is 0.02m/s√h.

Considering the flight time requirements of drones, this IMU has a power of only 1.5W, which can extend the flight time of drones.

This IMU has a short production cycle and can be mass-produced, which is particularly suitable for users with large demands and limited budgets.

What is an IMU and what can it do for your drone?

 

IMU is one of the core technologies of drone(UAV) systems. This information is the key to autonomous navigation, stable control and precise flight of UAVs. Some research teams have developed data-driven diagnostic methods centered on IMUs, using IMUs to diagnose faults for UAVs. IMUs usually contain embedded algorithms, such as sensor calibration and data fusion, which help simplify software development and system integration for UAVs.

ERICCO's MEMS IMU ER-MIMU-07 and ER-MIMU-03 (OEM customization is available) can be used in drones. They are small in size, superior in performance, light in weight, low in power consumption, and cost-effective, making them popular among users. With the advancement of technology, the performance of MEMS IMU continues to improve, while the size and power consumption continue to decrease, and they can be integrated into smaller drone platforms. Please see the picture for detailed parameters of MEMS IMU.

The core functions of MEMS IMU include measuring the linear acceleration, angular velocity, and direction of the drone. The accelerometer is responsible for sensing the acceleration and deceleration of the drone during flight, while the gyroscope measures the rotation of the drone. The data from these sensors is processed by advanced algorithms to provide real-time attitude adjustment and navigation information for the drone.

In the design and application of drones, high-performance IMUs can provide stable and accurate data under various environmental conditions, such as temperature changes, vibrations, and rapid movements. This enables drones to remain stable in complex flight environments and perform precise tasks such as aerial photography, logistics transportation, and agricultural monitoring.

With the continuous development of drone technology, we can foresee that MEMS IMU will play a more critical role in future drone applications, providing strong support for the intelligence and autonomy of drones.
