1. Apparatus for stabilizing the motion of an inertial load relative to a supporting member, comprising:
- an intermediate frame member, compliant isolation means connecting the intermediate frame member to the supporting member for providing limited translational motion of the intermediate member relative to the supporting member, pivot means connecting the load to the intermediate frame member, the pivot means allowing rotation of the load relative to the intermediate frame member about at least two mutual perpendicular axes of revolution, actuator means connected to the load and to the intermediate frame member for rotating the load relative to the intermediate frame member about each of said axes of revolution, and means for controlling said actuator means to adjust the angular position of the load relative to the intermediate frame about both said two axes of revolution.

Abstract
A stabilizing system for isolating a load device from vibrations of a supporting structure includes a pivotal member and a spring isolator connecting the load device to the supporting structure. Servo controlled actuators are connected across the pivotal member to rotate and torque the load relative to the isolator to compensate for angular displacement of the supporting structure and isolator relative to the load device. An inertial sensor secured to the load device provides a reference for the servo control.

8. Apparatus for stabilizing a load against rotational motion about two or more mutually perpendicular axes and to isolate the load from translational vibrational motion relative to a support, said apparatus comprising:
pivot means having two relatively moving sections, the first section pivoting relative to the second section about at least two mutually perpendicular axes passing through the pivot point of said pivot means, compliant isolation means connecting the first section of the pivot means to the support, the isolation means providing limited translational movement of the pivot means relative to the support, the second section of the pivot means being rigidly connected to the load, actuator means having a drive member rigidly connected to one of the two sections of the pivot means and a drive member rigidly connected to the other of the two sections for rotating the two sections of the pivot means relative to each other about each of said mutually perpendicular axis, inertial sensor means connected to the load, and servo means responsive to the sensor means for driving the actuator means to adjust the relative angular position of the two sections about both of said axes and to correct for rotational movement of the first section of the pivot means by the support. - View Dependent Claims (9, 10, 11, 12, 13)
