Based on the moving equation of gyroscope’s sensitive components which is founded by Euler dynamic equation

the theoretic moving model of gyroscope cursor is analyzed.Microcomputer automatic measuring system of gyroscope is designed which can collect the moving curve of cursor automatically

fit the data points

describe the real-time curve

compute the measuring result

magnify and reduce the curve

and so on.The amplitude spectrum and power spectrum of cursor moving curve obtained by Fourier transform show that the collected cursor curve accords with the theoretic curve in the main

which proves the feasibility of the automatic measuring system in north finding.
