ANTENNA CONTROL SYSTEM FOR A SHIP TERMINAL FOR MARISAT
The performance specification of the MARISAT civil maritime communications system demands a control system for the antenna mount to meet the requirements for acquisition, tracking and stabilization against ship motion. The required pointing accuracy is discussed in relation to the physical disturbances caused by ship motion. Various mount configurations are described from which a preferred arrangement is selected. The stabilization, acquisition and tracking systems are described, with comments on gyros and level sensors. A method of performance assessment is included.
