PURPOSE:To fire accurately a flying body even when the attitude changes irregularly by providing an attitude detector comprising a light transmitting case sealed with a liquid, a luminescent device and a sensor detecting a 2-dimension displacement. CONSTITUTION:In taking a photodetecting plane 8 of a sensor 7 as a plane coordinate and measuring the attitude with respect to a cross point between an optical axis 12 of a refracted light and the plane 8 as a coordinate, the attitude of the light transmitting case 1 is detected in the attitude detector by measuring the tilt of an optical axis to 6 to a perpendicular axis 10 as two angles on two planes including the perpendicular axis and being orthogonal to each other by a simple calculation. Since the attitude of a running vehicle 11 provided with a firing key 16 is measured as two angles on two orthogonal planes including the perpendicular axis and the azimuth angle and elevating angle to a target measured by a radar device 14 are corrected and decided by the coordinate system with respect to the perpendicular axis, a flying body is fired in an accurate direction by turning properly a turning base 17 and a flying body support 18 of the firing key 16. |
