    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%.

    Laser interferometers have generally been used for the angular measurement of measuring tape calibration systems. Yaw error measurements using a yaw sensor have been carried out to determine the characteristics of yaw errors and analyze the behaviors of the structural guide. The yaw sensor technique is identical to the error compensation used in a measuring tape calibration, and also has some special parameters. However, the yaw error observation period is very short, but it is sufficiently accurate for a carriage yaw sensor. This paper presents the yaw sensor innovation for the measuring carriage application that would be compensated by using yaw error is approximately minimized to 65 arcsec and its repeatability is less than 30arcsec.
