SAUV II - Lake George, NY Field Tests

June 1 - 11, 2004

The Lake George tests are being conducted by the Autonomous Undersea Systems Institute (AUSI), Technology Systems Inc. (TSI), and Falmouth Scientific Inc. (FSI) in collaboration with Rensselaer Polytechnic Institute's Darrin Fresh Water Institute (DFWI) research center.

The goal of the Lake George testing is to continue to evaluate and exercise the capabilities of the SAUV II AUV platform and sensors while conducting a scientific data gathering operation of extended endurance. To accomplish this goal, a number of objectives have been defined as summarized below:

• Perform extended endurance missions of 4 days or more in duration
• Evaluate the AUSNET protocol during in water testing
• Establish effective logistics support for SAUV II testing
• Acquire dissolved oxygen data in conjunction with the DFWI's RUSS buoy and verify the quality of that data
• Evaluate the ability to reason about energy acquisition and utilization based on acquired energy data
• Evaluate various communications modes on the SAUV II
• Evaluate the performance of the YOYO maneuver and the auto altitude capability of SAUV II

These tests are part of a broader program to research and develop technology and systems to enable Multiple Cooperating AUVs (MCAUV), and is funded through ONR and NSF. During this testing period, the main thrust of the MCAUV effort is to verify the performance of the SAUV system while undertaking extended deployments and to verify the capability to communicate via RF (Freewave) links and geo-synchronous communication satellites (Iridium). This field effort will also focus on evaluating a first level of capability using the underwater networking AUSNET protocol between multiple nodes.

Current Vehicle Status (2 PM, June 11)

Testing complete.

The SAUV II vehicle is equipped with the capability to allow it to update a simple on-board web html document with information about itself. While testing with the vehicle, we will periodically retrieve this web page from the SAUV II and archive it to our land-based Internet server for users to view.
