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.
