This paper describes a method for the precise postprocessed
positioning of a deep-diving autonomous underwater vehicle
(AUV) using only a set of acoustic ranges from a surface ship
while the AUV executes a closed path under the ship. This approach
avoids the use of either a precisely calibrated (and consequently
expensive) ultrashort baseline (USBL), or a long baseline
(LBL) system (which is expensive in ship time to deploy). Results of
Monte Carlo simulation and field results from the first trials of the
Autosub6000 AUV are presented to support the hypothesis that an
AUV at 6000-m depth can be positioned to an accuracy commensurate
with global positioning system (GPS) quality or better, within
a period of 1 h.
