Scale factor - definition of scale factor by The Free Dictionary

WebSep 23, 2008 · Scale factor and bias are different kinds of deterministic errors. A bias results when the gyro registers some non-zero rate when the gyro is in fact not rotating. Suppose you have compensated for the gyro bias and it reads a rates 0.11 and 0.22 radians per second when the gyro is actually rotating at 0.1 and 0.2 radians per second, respectively.
