Each MEMS gyroscope undergoes rigorous performance testing and calibration of sensitivity and zero-rate output values before leaving the factory.
Calibration is to solve the error coefficient by comparing the difference between the actual measurement output of the sensor and the preset reference value, and constructing the relationship between the measurement output and the expected output, so that the measurement output of the sensor tends to be consistent with the ideal output. According to the different preset reference values or reference objects, it can be divided into two categories: autonomous calibration and non-autonomous calibration. The specific difference lies in whether the assistance of high-precision laboratory equipment is needed, that is, error calibration through attitude reference data provided by large precision instruments.
1. Non-autonomous calibration: This kind of calibration requires the assistance of well-structured precision instruments, such as high-precision turntables, centrifuges, shakers, etc.
2. Autonomous calibration: This calibration is completed using external reference excitations provided by the local gravity field, earth rotation angular velocity, uniform magnetic field, etc. without the assistance of high-precision instruments.
