Abstract : A discrete state space model is developed which describes an autonomous underwater vehicle and incorporates the effects of currents, sea state, and wind as it travels through the sea. Heading commands are calculated to overcome these effects by the design of an Extended Kalman Filter which estimates their combined velocity components. Simulations are done which test the filter's effectiveness in a range of different environments. Some potential uses for this system are discussed at the end.
