            Abstract : 
A two-layered hierarchical guidance and control architecture for UUVs has been integrated with a set of model-based motion estimators in order to enable the execution of high precision motion tasks in proximity of the seabed for scientific benthic applications. Preliminary tests, carried out in a high-diving pool, proved the system functionality, showing the high performances in terms of precision guaranteed by the use of PI-type guidance algorithms and combined estimation of the vehicle depth and altitude in hovering conditions
