How to correct when there is an error in the inertial device?

 An inertial measurement unit (IMU) is an electronic device that uses accelerometers and gyroscopes to measure acceleration and rotation and can be used to provide position data.

So today we will learn how to correct the error of the inertial device?
The following are some calibration methods for reference only.
Calibration method
(1) Calibration of internal parameter error of inertial device
(2) Discrete liquid level calibration
(3) Semi-system level calibration
(4) System level calibration
Comparison of different types of calibration methods
(1) The discrete-level calibration accuracy is higher, but it depends on the turntable.
(2) The calibration accuracy at the semi-system level is the worst, but it does not rely on a turntable, has low cost and high efficiency, and meets the calibration requirements of MEMS.
(3) System-level calibration has the highest accuracy, but it is only suitable for high-precision inertial navigation calibration.
Then the ER-MIMU-01 developed by Ericco uses high-quality and reliable MEMS accelerometers and gyroscopes. It communicates with the outside through RS422. The baud rate can be flexibly set between 9600~921600. The communication baud rate required by the user can be set through the communication protocol. . Equipped with X, Y, Z three-axis precision gyroscope, X, Y, Z three-axis accelerometer, with high resolution, it can output the original hexadecimal complement of X, Y, Z three-axis gyroscope and accelerometer through RS422 code data (including gyroscope hexadecimal complement) numerical temperature, angle, accelerometer hexadecimal temperature, acceleration hexadecimal complement); it can also output gyroscope and accelerometer data that have been processed by underlying calculations Floating point dimensionless value.
