    A high resolution yaw sensor employed widely for observation the small angle measurements and angular applications. It needs to calibrate with high accuracy of standard for achievement of their performance and traceability. The measurement uncertainty evaluation of yaw sensor calibration is also necessary. This paper presents the technique of measurement uncertainty evaluation of yaw sensor following the guide to the expression of uncertainty in measurement (GUM). The uncertainty evaluations were approximately minimized to 40 arcsec, the confident level approximately 95%.

    Most recently, the measurement uncertainty evaluation employs entirely for evaluating the measurement process which is also use to investigate the residual error of length measuring system. This paper presents the measurement uncertainty of the reversal errors that would be compensated by using the error with the measurement uncertainty compensation module. The confident level of measurement uncertainty is approximately 95%. This evaluation result of the measuring system errors were approximately minimized to 8.0 μm.
