Solar AUV (SAUV II)

FSI's Solar AUV (SAUV II) is a solar-powered autonomous underwater vehicle providing extended mission endurance on the surface or at depths up to 500 meters. On-board rechargeable lithium-ion batteries provide maximum mission endurance even under conditions where minimal solar radiation is available. The SAUV is designed as a multi-mission platform to allow payload configuration by the end-user to optimize the SAUV for coastal/harbor monitoring, data portal (to moored sub-surface instruments) applications, or any other application where long-term deployment is required. The SAUV is designed to reside on the surface while recharging batteries and then to execute its programmed mission. While on the surface the SAUV is designed to communicate via Iridium satellite or RF communications link to upload collected data and to allow reprogramming of mission profiles. A bi-directional acoustic link provides for data acquisition from sub-sea instrumentation. The vehicle can be pre-programmed to submerge to depths down to 500 meters, to transit to designated waypoints, or to operate on the surface during conditions suitable for battery charging via solar energy input. Developed jointly by FSI, The Autonomous Undersea Systems Institute (AUSI), and Technology Systems, Inc. (TSI), the SAUV is an extremely flexible platform for a wide range of missions, with a unique combination of energy availability and ability to dive or remain on the surface. ---------------------------------------------- Visit AUSI and AUVAC (Autonomous Undersea Vehicle Applications Center) sites for additional information on the SAUV II. ---------------------------------------------- Why Choose a SAUV?
