Analysis & simulation of an advanced inertial stabilization concept

The Internal Bearing Stabilized Sighting Unit (IBSSU) is an innovative concept in precision stabilization for high resolution electro-optical sensors mounted in high disturbance vehicle environments. It is an inertially stabilized platform supported by “soft mount” isolators to reduce the effects of vehicle vibration and gunfire on the performance of the sensors. The unit was analyzed and a simulation program written to aid in the evaluation of this advanced inertial stabilization concept. IBSSU is described and the equations of motion showing the coupling between translational and angular motion are listed. The simulation program is used to compute the platform response to disturbance inputs. IBSSU laboratory test data are used to validate the model.
