Abstract:ABSTPACTA high resolution acoustic navigation system for ocean use is being developed at the Woods Hole Oceanographic Institution. The system can yield navigation fixes with respect to a bottom moored reference net with accuracies (on a fix to fix basis) of a few centimeters.In order to use the system to best advantage a survey is required to determine precisely the relative positions of the net elements.Each element combines a pulse transponder with a continuous wave (CW) beacon. Accumulated phase (Doppler s… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
