Introduction

Gyroscope is widely used in various fields of national economy, its static characteristics are associated with calibration specifications or test method, Dynamic characteristics of the country still do not have the technical regulations, based on this consideration, combined with the dynamic characteristics of the gyroscope calibration real Actual situation, referring GJB2425A-2004 "Test Method for Fiber Optic Gyroscope" Writing this specification.

Gyroscope dynamic characteristics calibration specification

1 Scope

This specification defines the gyroscope dynamic characteristics calibration items and calibration methods for SDOF rate gyro Instrument, multi-DOF rate gyroscope for implementation.
