The accuracy of an optical gyro is largely dependent on the length of the light transmission path (larger is better), which is constrained by the size of the device. 3.1.3 MEMS ... Web4 de jun. de 2024 · For an MEMS gyro, errors may result from environmental factors, for example, temperature. In addition, inherent noises can arise because of inner electric circuit features. Statistically, errors of an IMU can be divided into two types: systematic errors and stochastic errors [ 11 ].
