Abstract
The purpose of the contract is to evaluate the feasibility and accuracy of long-baseline, range-range, towfish positioning. The configuration calls for a paravane or workboat-outfitted with positioning, ranging, and modern equipment-to travel in a parallel course, but at some offset, to that of the towfish. The result is a triangulation method to accurately position the towfish. A system was configured and installed aboard the Endeavor, Yag, and a towfish. In the static test, the towfish was anchored to the ocean bottom while the two vessels drifted in the area above. In the dynamic test, the Endeavor ran standard lines towing the towfish at standard dpehts with the Yag following in a parallel, but offset, course.
