Solar-powered AUV (SAUV) Vehicle/Mission Status

Lake George Multiple Vehicle Simulated Test
May 30 - June 9, 2006

The principle objectives of the Lake George testing are to:
  1. Provide a dress rehearsal for the July 2006 Monterey Bay exercise where multiple SAUV vehicles will cooperate to acquire scientific data to be utilized by the LOCO (Layered Organization in the Coastal Ocean) scientific team
  2. Support the NSF-sponsored RiverNet project through a SAUV mission to sample the Hudson River
  3. Demonstrate technology development efforts which support multiple cooperating AUVs
The Lake George tests are being conducted by the Autonomous Undersea Systems Institute, Technology Systems Inc., and Falmouth Scientific Inc. in collaboration with Rensselaer Polytechnic Institute's Darrin Fresh Water Institute research center and the Naval Undersea Warfare Center. These tests are part of a broader program to research and develop technology and systems to enable multiple cooperating AUVs, and is funded through ONR and NSF.

Current Mission Status as of Wed Feb 28 17:10:12 2007

SAUVs 1 and 2 are currently performing cooperative survey mission near Fourteenmile Island. Both vehicles are sampling DO, water temperature and conductivity. SAUV 3 is enroute to Hudson River site for day test.
Status Powered on, running lawnmower survey task. On last leg of mission. Powered off, tied up at watch circle #1 buoy. Powered on, low on energy.
