Subsea Wireless Modem and Datalogger10/05/2012
|Seatooth S100 from WFS Technologies is the latest wireless subsea modem from the WFS seatooth range, officially launched at the Offshore Technology Conference 2012 in Houston, Texas, USA. A mobile, compact, low-power, wireless modem suitable for a variety of underwater applications with an optional 8MB integrated memory for use as a datalogger, the device will provide a reliable digital wireless communication link or act as a logging device up to 3m, even in challenging deepwater conditions (with no wet-mate connection).|
Seatooth S100 is available in a variety of configurations. A selection of housings offers various depth rating options from 100m to 3000m and an unpackaged OEM version available for easy integration. S100 has standard interfaces for wireless data communication with underwater vehicles and so can be set up swiftly for a temporary plug-and-play deployment.
Power consumption is optimised for longer missions with a 'wake up from sleep' function where the modem turns on if radio signal/serial data input is detected. S100 offers a choice of external power or internal battery pack dependent on application.
Integration of S100 for subsea operations offers benefits in safety: additional layer of redundancy for challenging operations or independent storage and data recovery for black box applications, improved efficiency as no hard cabling is required, simple deployment and retrofit and access to wireless sensors in hard-to-reach areas as well as being cost-effective compared to a dedicated data retrieval mission. It is particularly suited to integrity management applications with real-time, shorter download times, and faster access to data. It also requires no wet mate connectors, offers reduced cost of intervention, and surface support is not required.
Seatooth is a range of subsea modems that transmit data and video through water and through the water-air boundary. Available as a standard-sized modem, as a hybrid solution with camera, acoustic or power transfer capability, or as PCB only for OEM integration, seatooth signal is not affected by an acoustically noisy environment, presence of contaminants or by the effects of shallow, congested or turbid waters, thus making it suitable for applications in an offshore environment.

Demo of RIEGL Airborne Bathy Scanner in Camcopter UAV
It's not an AUV but an UAV. So an unmanned vehicle, but in the air instead of underwater. This movie shows a demonstration of the bathymetric laser scanning capabilities of the RIEGL VQ-820-GU hydrographic airborne sensor in reality. For more information on the technical side, please see the news release on Hydro International.
