The key to achieving autonomous navigation, stable control and precise flight of drones is closely related to IMU, which is one of the core technologies of drone systems. At present, there are also research teams that have developed IMU-centric data-driven diagnostic methods to perform fault diagnosis on drones without the need for additional sensors. Choosing the right IMU can make flight more stable and safer.
ERICCO's MEMS IMU ER-MIMU-07 and ER-MIMU-03 (can be customized for OEM) can be used in drones. Using MEMS technology, they are small in size, superior in performance, light in weight, low in power consumption, and cost-effective, and are very popular among users.
Drones have strict requirements on the size and weight of IMUs. The ER-MIMU-03 has a size of (43.2×43.2×35.5mm (without shell), 65×70×45.5mm (with shell)) and a weight of (≤100g (without shell), ≤220g (with shell).
The ER-MIMU-07 is a very small IMU, measuring only 38.6 x 44.8 x25.5mm and weighing less than 70g, which is suitable for drones with higher IMU requirements.
Flight control of drones is one of their most basic functions. MEMS IMU helps drones maintain a stable attitude by providing real-time acceleration and angular velocity data.
The gyroscope measurement range of ER-MIMU-03 and ER-MIMU-07 is ±400deg/s, bias instability <0.3deg/hr, angular velocity random walk <0.15°/√h, accelerometer bias repeatability 5mg, and second-order nonlinear coefficient <100μg/g2. At the same time, it has the characteristics of low power consumption, which prolongs the flight time of drones.
It can also combine data from other sensors (such as GPS, magnetometer, etc.) to calculate the precise location and attitude information of the drone for navigation and positioning. When the drone is taking aerial photos, it can maintain extremely high stability to ensure the clarity and stability of the images and videos taken. At the same time, it can also be used as part of the drone's fault safety system to detect abnormal movements or attitude changes and trigger automatic recovery procedures or emergency landing procedures to protect the safety of the drone and the surrounding environment.
In the design and application of drones, high-performance IMUs are able to provide stable and accurate data under various environmental conditions, such as temperature changes, vibrations, and rapid movements, and perform precise tasks such as aerial photography, logistics transportation, and agricultural monitoring.
MEMS IMU has many applications in the field of drones. They not only improve the performance and stability of drones, but also expand the scope of application of drones.
