Abstract
Tracking system that operates from nonstationary platform must have some means to stabilize the tracking axis for precision tracking. There are several methods used on a tracking axis stabilization. Among them, implementation of a free gyro pointing assembly which has momentum wheel that is an integral part of the innner gimbal assembly and that is orientated its spin asix parallel to the line of sight, is the most widely used methods for tactical missiles because of its simplicity and cost effectiveness. The paper describes two methods to improve stabilization of this tracking system by adjusting gimbal balance during accerelated condition and adjusting gimbal friction torque at an optimum level appropriate to the applied torque. The result shows one fifth improvement of the drift rate compared to the presently used tracking system, achieved more precision tracking.
