This thesis addresses the improvement of a physically based modeling simulator Naval
Surface Tactical Maneuvering Simulation System (NSTMSS), that combines different simulators
in a distributed environment by the help of High Level Architecture (HLA), to be
used in naval tactical training systems. The objective is to upgrade a computer simulation
program in which physical models are improved in order to achieve a more realistic movement
of a ship in a virtual environment. The simulator will also be able to model the ocean
waves and ship wakes for a more realistic view. The new naval model includes a 4 degrees
of freedom (DOF) maneuvering model, and a wave model. The numerical results from real
life are used for modeling purposes to increase the realism level of the simulator. Since the
product at the end of the thesis work is needed to be a running computer code that can
be integrated into the NSTMSS system, the code implementation and algorithm details are
also covered. The comparisons between the wave models and physical models are evaluated
for a better real time performance. The result of this thesis shows that the integration
of a 4-DOF realistic ship model to the system improved the capability of NSTMSS to give
more data to the student officers while making maneuvers. The result also indicates that
the use of waves and ship wakes had taken the simulator to a next level in the environment perception.
