Developing higher performance autonomous underwater vehicles (AUV) that are smaller and less complex, Team SONIA, comprised of students from the École de technologie supérieure (ETS) in Quebec, Canada, have integrated Texas Instruments Incorporated’s (TI) (NYSE:TXN) TMS320F28x digital signal controller (DSC) technology into their new vehicle, which will compete in the 10th International Autonomous Underwater Vehicle Competition in San Diego, July 12-15, 2007. The SONIA autonomous underwater vehicle (AUV) will compete in complex tests designed to advance subsurface navigation technology for use in dangerous, difficult and expensive real-world underwater applications.
