Afficher plus [+] Moins [-]Accurate velocity of an ocean going vessel with respect to the water can be determined in real time by utilizing a Doppler Current Profiler (DCP) system. The DCP employs multiple sonar beams with a plurality of bins or returns from various depth segments. These returns are then statistically processed to attain stable and accurate velocity information. The process is performed without any temporal averaging allowing it to be employed where raw data requirements must be met such as the damping of inertial navigation systems.
