dc.description.abstract This thesis presents the design and simulation of an acoustic listen-only navigation system for use in a time-varying high-multipath environment. The system uses a ray tracing model of sound propagation in a horizontally stratified ocean to associate each multipath arrival with a particular ray path through the ocean. This ray path identification allows an inversion for both vehicle position and sound speed profile parameters. Tracking changes in the sound speed profile allows the vehicle to maintain navigation accuracy in a time-varying acoustic environment. Simulation results for typical Arctic conditions indicate the potential for accurate navigation from acoustic beacons at ranges up to tens of kilometers. en_US
