Abstract

A novel type of angular velocity calibration standard is under development at NMIJ. The system is equipped with a self-calibratable rotary encoder (SelfA), which is same apparatus as one of the national angle standards in Japan. SelfA is also useful to ensure angular traceability in a simple and robust way. This facility will be mainly utilized to provide angular velocity standard for MEMS gyroscopes which become widely used in automobile industries. In this paper, demands for angular velocity standard, advantage of using a SelfA and initial experimental results of the facility will be presented.
