The track keeping characteristics of an autonomous ocean vehicle in the presence of a realistic time lag on the vehicle's position information is examined in two ways. A Hopf bifurcation analysis is applied to better predict vehicle behavior within its region of linearized classical stability. Additionally, the effects on guidance /control stability by the use of a single stage memory model incorporating the two previous vehicle positions in place of a single position data point is investigated. Results are presented using a dynamic model of the Naval Postgraduate School Autonomous Underwater Vehicle II (NPS AUV).
