Doppler Velocity Logs (DVLs) have become increasingly popular as navigation tools on remotely-operated vehicles, autonomous underwater vehicles, and human-occupied vehicles for over a decade. Using acoustic measurements to capture bottom tracking velocity measurements, DVLs can provide updated velocities which can in turn be used to calculate distance traveled. Thus, DVLs can perform as fundamental...
This paper presents a remote control system of a 6 DOF underwater robot using two acoustic transducers, while radio and optical waves are not used because they are strongly attenuated in a complex environment as water. Underwater robots can be controlled by cables limited by distances, environment conditions, and not flexible. Therefore, it is necessary to develop a remote control system for underwater...
Undersea communications and navigation for UUVs are usually accomplished using separate onboard and off-board systems. Communications capabilities are typically reserved for command and control of the vehicle, and/or to move data from the vehicle to a gateway. As part of several US Navy programs, Teledyne Benthos has developed the Directional Acoustic Transponder (DAT), which uses a modified ultra-short-baseline...
