PURPOSE: To reduce a time of stabilizing the gyrocompass and to improve the measurement precision by using three control means in which a certain relation between the gain of both the precession around the vertical and horizontal axial lines and the angle of inclination of the gyrocompass and the gain constant is held.
CONSTITUTION: The block 38' that consists of a stabilizer or an inclination detector, amplifier and torquer is made up so that the gain described in it may be provided, and the block 39' that consists of a damping weight or the inclination detector, amplifier and torquer is made up so that the gain described in it may be provided. When a direction ϕS is obtained from these formulas and a specific equation is made up, a solution of the equation (S+K1/K)[S2+2ζ(KΩcosλ.S/H)1/2+ KΩcosλ/H]=0 can be obtained. Also when 2π/ω0 is taken as the period, the equation (S+1/T)(S2+2ζω0S+ω02)=0 can be obtained, and a value obtained by dividing the gain of the block 39' by the angular momentum H can be provided from these solution.
