KAUAI BEACON RESEARCH

Abstract

The Applied Physics Laboratory at the University of Washington (APL-UW) has a low frequency electro-acoustic underwater transducer,,designated HX554, located off-shore of the island of Kauai, and command and control hardware located at a shore station at Pacific M,issile Range Facility, Kekaha, Kauai. The undersea cable and the shore station equipment were repaired in 2021. The effort described, here proposes using the system for underwater navigation beacon research and development, and also long-range, low-frequency ocean,acoustic tomography. The navigation signals will be transmitted to autonomous underwater research vehicles during occasional experim,ents in and around the Hawaiian Islands. The tomography signals will be transmitted over multi-megameter distances on a sub-2% duty,cycle to receivers operated by collaborators along the North American west coast. Shore station hardware, most of which is 15 years,old or older, will be gradually upgraded.
