Do you know why IMU is an irreplaceable part of drones?
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.
