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. Some gyros … Ver mais Web20 de nov. de 2024 · The gyro error is rarely more than one or two degrees for a correctly maintained gyro.
