Solar-powered AUV for Plate Survey12/01/2010 |
| Falmouth Scientific, Inc (FSI) has supplied a solar-powered Autonomous Underwater Vehicle (SAUV) to the University of Tokyo for use in monitoring tectonic plate movement. The SAUV is a compact, man-portable AUV designed for autonomous operation for long periods (weeks to months) without requiring maintenance, servicing, or recharging. |
|
The vehicle can be pre-programmed to submerge to depths down to 500 metres, to transit to designated waypoints, or to operate on the surface during conditions suitable for battery charging via solar energy input. With a square metre of solar panels, the SAUV can collect from 300 to 900 Watt-hours per day and carries 2.4kWh on-board, rechargeable batteries, providing sufficient power for extended missions with large user payloads and frequent communications.
For this project, the SAUV has been equipped with a specialised transducer to receive precise slant range data from seabed-mounted transponders along with an RTK GPS, IXSEA PHINS motion reference unit and a TRDI WorkHorse ADCP. The SAUV provides the large payload capacity and stability that make this project possible. The combination of precise data from the underwater transponders, RTK GPS, and IXSEA MRU will allow researchers to monitor tectonic plate movements on the scale of millimeters per kilometre.
The SAUV was delivered through SEA Corporation, FSI's representative in Japan. Read more about: RTK AUV ADCP Website: http://www.falmouth.com/products/SolarAUV.html Supplier: Falmouth Scientific Inc.

Hydrographic Survey of Riverbed Erosion |
Members of the US Geological Survey were filmed while out on the Missouri River at Williston, North Dakota, USA, performing a hydrographic survey to monitor the state of riverbed erosion. They were using a multibeam echo sounder which transmits sound energy and analyses the return signal (echo) that has bounced off the riverbed or other objects. Multibeam sonars emit sound waves from directly beneath a ship's hull to produce fan-shaped coverage of the riverbed.
