Navigation Software for the MPL Vertical Line Array

Abstract

This report describes the navigation software and demonstrates its operation using data obtained during an experiment in which a large aperture low frequency acoustic array, designed and built at the Marine Physical Laboratory (MPL), was deployed vertically from the Research Platform FLIP in the NE pacific. The array was equipped with a 12 KHz acoustic navigation subsystem. Travel time measurements from near bottom acoustic transponders of known position were received by specific array elements throughout the deployment. These measurements were converted to spatial positions of the array elements by a nonlinear least squares technique. The data collection methods and navigation software programs which locate the transponders, calculate the travel time from detected returns and convert travel times to spatial positions are documented.
