Canada and many of its allies have recognized the utility of modelling and simulation for acquisition, life-cycle management, training, tactics and doctrine development, and other applications. Canada is currently developing a distributed simulation of Replenishment at Sea (RAS). Initially, the simulation may be used as a tool in the acquisition process, but it is foreseeable that a distributed model of multiple ships in close proximity will be of use in many diverse applications. One of the key properties of any computer model is its fidelity to the real object behaviours. It is therefore necessary to gather data from the real operations in order to validate the models and to increase the level of fidelity. The aim of the Development Evaluation undertaken in June 2006 was to observe RAS operations and gather data (ship motions in particular) for use in development and validation of computer models of ships in close proximity. In particular, measurements were taken to quantify the variations in ship motion due to proximity of ships and/or physical connections during RAS operations. A secondary aim is to verify that the combination of motion packs and GPS data will provide a practical, complete motion solution for both individual ship motion and relative motion between ships. The goal was to observe normal operations, gathering data on small portable logging units (motion packs and GPS receivers), without interfering in the ship’s routine. The Development Evaluation took pla
