PURPOSE:To oscillate bearing signals having no gimbal errors with simple and inexensive constitution by detecting the revolving angles of a gimbal mechanism around a roll shaft and a pitch shaft, and operating and correcting gymbal errors. CONSTITUTION:The detection signals of the rotating angle of a gimbal 3 around a roll shaft and the rotating angle around a pitch shaft from angle detectors 5, 6 are inputted to an arithmetic unit 14, by which gimbal errors are calculated. The error signals thereof are inputted together with the signal from a linear pickoff 10 to a servoamplifier 15. A servomotor 9 transmits the correction revolution for the gimbal errors with respect to the 1st servomotor 7 to a gear 11, by which a synchronous transmitter 13 is also cooperatively rotated and the transmission having no gimbal errors is accomplished. Thereby, the transmission having no gimbal errors is accomplished with the simple and inexpensive constitution. |
