Analysis of Direct Mechanical Stabilization Platform for Antenna Stabilization and Control in a Shipboard Environment

Abstract

This report presents a rigid body analysis of the dynamics of a shipboard antenna in a three-axis gimbal configuration utilizing Direct Mechanical Stabilization (DMS) for primary control. System parameters are defined and Euler equations applied to obtain a non-linear system model that includes expected torque inputs. A computer simulation is generated with ship input motions due to roll, pitch, turn and flexure and a numerical integration procedure is then employed to determine the motion of the antenna and the resulting pointing error for various scenarios. The results of the cases studied indicate potential feasibility of this approach for applications requiring pointing accuracy of approximately + or - 0.15 degree.
