Shipboard Stabilization of Optical Systems.
Abstract
The control system for an existing shipboard gyrostabilized optic tracking platform was redesigned to achieve a longer tracking capability and improved tracking stability. The redesign increased the gain of the detector amplifier chain and improved the control system linearity. These modifications in conjunction with the addition of a mechanical viscous damper resulted in a three-fold increase in tracking range capability and significantly improved tracking stability and reliability. The maximum tracking range of the system was estimated to exceed 6000 meters. The system tracking uncertainty is approximately + or - 2.5 milliradians under 'sea state' 5 and is less than this under normal conditions. (Author)
