PURPOSE:To order a moving object such as aircraft to move along the course as specified by checking to see whether the moving object is moving along two scanning surfaces formed with the scanning of sharply directional signals. CONSTITUTION:If a detector 31 provided on a main wing detects a laser beam 20a scanned vertically at the center of an aircraft 1, a horizontal direction controlling circuit 51 won't works a direction rudder mechanism 61. For example, when a detector 31 on the left main wing detects a laser beam 20a, the horizontal direction controlling circuit 51 works a direction rudder controlling circuit 61 to turn the direction rudder to the left. A detector 32 provided on a vertical tail wing detects a laser beam 20b horizontally scanned. After amplified with an amplifier 42, detection signals are applied to a vertical direction controlling circuit 52 to determined a deviation of the aircraft 1 with respect to the vertical course based on output signals. A lift rudder control mechanism 62 works to lift the aircraft when it is below the level formed by the laser beam 20b. |
