Abstract

PURPOSE:To perform digital and simple phase control of two bodies of revolution by controlling a pulse motor by providing a multi-frequency pulse generator, reversible counter which counts reversibly on the basis of the needle-handling direction of a boat, and comparator. CONSTITUTION:Antenna 11, driven by motor 12, and deflecting coil 14 of a Braun tube, driven by pulse motor 15, are turned in phase by bow-line synchronizing circuit 16. On every rotation of antenna 11, azimuth pulse generator 17 generates a string of pulses of frequency (f), which are supplied to selection gate 18 direct or through multiplier 20, and dividers 21 and 22. In accordance with a change in course, signals from setter 26 and gyrocompass 23 are supplied to 1st and 2nd reversible counters 25 and 29, whose outputs are compared each other to control selection gate 18. Consequently, pulse motor 15 is driven by several strings of pulses to control easily rotations of antenna 11 and deflecting coil 14.
