A pedestal and gimbal assembly related to missile semiactive radar seekers for supporting three gyroscopes and functions as a reference platform to relate airframe attitude. This is mechanized by utilizing the two degrees of freedom gimbal for pitch and yaw and controlling the missile body roll axis for the third degree of freedom. Structure of the positioning system includes a pedestal having an inner gimbal assembly including a support for mounting the antenna assembly and the gyros. A yaw torque motor assembly is carried by the inner gimbal and is provided with a pair of output shafts for supporting the inner gimbal and controlling the yaw movement thereof. A pitch motor is housed in the pedestal and includes a drive pinion and a drive shaft. The drive pinion is connected to the drive shaft. The drive pinion and yaw motor operates to control the pitch movement of the antenna assembly. (Author)
