A method is presented for determining the deck motion of an aircraft carrier in terms of the local reference coordinate system of the ship. Determination of motion is a prelude to prediction, and prediction is required to facilitate safe landing operations under all weather conditions. Both determination and prediction are necessary in terms of the same local reference coordinate system as that used by the landing aircraft themselves. The finding of the deck motion is deterministic rather than stochastic, inasmuch as the probability of knowing the sea state at any given time and place and the ship's dynamic response thereto is less than the probability of a landing accident not occurring. The motion would be determined by a differential analyzer solving a system of six differential equations of ship motion. Inputs to the differential analyzer are readings of the accelerometers and the latitude and longitude data of the ship. The accelerometers are fixed to the body axes of the vessel, and 'stable platforms' are therefore not required. Computation is thus performed only by electronic means. (Author)
