High gyro error
While bias stability has been long considered the “gold standard” specification for gyros, in the real world, vibration sensitivity is often the more severe performance limitation. Selection of a gyro based on its vibration rejection capabilities is sensible as other parameters can be easily enhanced via calibration or … Ver mais All low and moderate cost MEMS gyros exhibit some time-zero null bias and scale factor errors, as well as some variation over temperature. … Ver mais Ideally a gyro would measure only rotational rate, and nothing else. In practice, all gyros have some sensitivity to acceleration due to asymmetry of their mechanical designs and/or micromachining … Ver mais As mentioned earlier, most gyro applications are in situations where movement or vibration is present. Typical error budgets for the gyros shown in Table 1 used in various applications are shown in Table 2 using the … Ver mais Many applications routinely have short term abuse events that, while not damaging to the gyro, produce large errors. Presentation of a few examples follows.

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 ...
