[Of a gyro or accelerometer] The difference between the scale factor measured with positive input and that measured with negative input, specified as a fraction of the scale factor measured over the input range. Scale factor asymmetry implies that the slope of the input-output function is discontinuous at zero input. It must be distinguished from other nonlinearities.  1, fiche 1, Anglais, - scale%20factor%20asymmetry

Angular rate gyro accuracy is characterized by two parameters: scale factor and drift. The scale factor describes the capability of the gyro to accurately sense angular velocity at different angular rates. This value is used to convert the voltage output from the gyro into an angular rate. System imperfections can cause small variations in the scale factor. These variations appear as a factor at the output of the gyro. Gyro drift characterizes the ability of the gyro to reference all rate measurements to the nominal zero point.  3, fiche 2, Anglais, - scale%20factor

The scale factor is generally evaluated as the slope of the straight line that can be fitted by the method of the least squares to input-output data... For some sensors the scale factor may be expressed as a reciprocal.  2, fiche 2, Anglais, - scale%20factor

Le facteur d'échelle est généralement évalué comme la pente de la ligne droite qui peut être ajustée par la méthode des carrés minimaux appliquée aux données d'entrée-sortie obtenues en faisant varier l'entrée de façon cyclique sur la gamme d'entrée.  2, fiche 2, Français, - facteur%20d%27%C3%A9chelle

... for a mechanically dithered RLG [ring laser gyro], non-linearities(sidebands) appear in the input-output scale factor curve for an input rotation rate which is a harmonic of the dither frequency... There are two disadvantages to dithering. One is that the rotation rate periodically passes through zero where lock-in occurs. This results in a "random walk" angular position error. The other is that the vibration of the gyro body may affect other components or the gyro may be affected by other vibration sources. The laser gyro need not be mechanically dithered. The same result may be achieved by optical devices.  1, fiche 3, Anglais, - mechanically%20dithered%20RLG
