This paper reports the development and experimental evaluation of a simple and intuitive framework for obtaining steady-state maneuvering characteristics of a wide class of underwater vehicles. The possible use of steadystate characteristics includes navigation, fault-detection and vehicle design evaluation. The presented algorithms allow unknown currents to be included in the identification loop. Measured or estimated vehicle position, velocity and attitude are required inputs. The
