Overview

The C-Star is a 1-metre hand-deployable autonomous surface vehicle (USV) powered by wind and solar energy. Designed for persistent wide-area ocean intelligence, it operates individually or in constellations to collect real-time met-ocean data including wind speed/direction, sea surface temperature, air temperature, pressure, and humidity. C-Stars transmit via Iridium SBD satellite and can endure 100+ days at sea. The platform became the first USV to collect data from inside a Category 5 hurricane.
