1. A gyroscopically stabilized apparatus for aiming an instrument at a target object, the apparatus comprising:

  • hub shaft means including a pair of hub shafts disposed along a first axis and having opposite extremities, respectively;

    an instrument platform for supporting an instrument;

    a hub assembly including first bearing means defining the first axis and supporting the hub assembly upon the hub shaft means for rotation of the hub assembly about the first axis, the hub assembly including second bearing means defining a second axis perpendicular to the first axis and supporting the instrument platform upon the hub assembly for rotation of the instrument platform along a rotational path extending about the second axis;

    a gyro platform including a plurality of gyroscopes tending in operation to stabilize the gyro platform in space;

    third bearing means supporting the gyro platform upon the instrument platform for rotation of the gyro platform along a rotational path extending about the second axis;

    yoke means coupled to the hub shaft means and comprising a yoke having a half circle configuration, a midportion and opposite extremities, and coupled at its midportion to the support means, and coupled at its opposite extremities to the opposite extremities of the pair of hub shafts, and located outwardly of the rotational paths of the instrument platform and the gyro platform whereby the instrument platform and the gyro platform are rotatable about the first and second axes without engaging the yoke means; and

    support means coupled to the yoke means for supporting the hub assembly for rotation of the hub assembly about a third axis perpendicular to the first and second axes.
