PURPOSE:To correct the inclination of an oscillator and make it accurately follow the rolling or pitching of a ship, by driving the oscillator by means of an electrical signal having an average waveform of a desired number of waves. CONSTITUTION:The output of a potentiometer 17 to detect the inclination of an oscillator 14 is inputted through a switch 22 to n memories 231-23n and stored therein. An average waveform signal of n waves is formed in a divider 24. Said signal is divided by n in a divider 25 and inputted to an adder 20. The output of a potentiometer 10 connected to an oscillator 6 is added thereto and inputted to a comparator 21, which compares the output of the adder 20 with that from a set voltage generator 19, the voltage being set through a knob 18. A driving motor 13 is driven so that the output of the comparator 21 becomes zero. Thereby, the inclination of the oscillator 6 is corrected. |
