Abstract
The XSVA is a 24-element vertical array of temperature and conductivity sensors, integrated into a standard sonobuoy, providing continuous estimates of sound velocity over a 72-hour measurement period. In Phase I, Areté Associates demonstrated the key elements of the XSVA array concept. We built and tested a breadboard sensor module, the backbone of the array. This module will make the parameter measurement, control power, and parse data, requiring only one wire and seawater return. In Phase II, Areté will develop, build, and test a small number of prototype, XSVA arrays. Areté will field test the prototype XSVA arrays on a platform of opportunity, if time and schedule permit. Areté has included a Phase II option task to allow leasing an aircraft or ship if a platform of opportunity proves not to be available. We also have included two additional option tasks that would enhance the capability of using a sonobuoy for a three-day period or longer.
