NEOEx Systems, Inc. proposes to use advanced energy and power systems technology to significantly improve Unmanned Aerial Systems (UAS) endurance and capabilities required to meet the NOAA NWS anticipate mission scenarios. Our innovative approach integrates high technology readiness level power and energy subsystems into existing and proven commercial off the shelf aeronautical subsystems for airframe, aerodynamics, propulsion, and guidance and navigation to conduct autonomous operations that exceed over 50 hours of endurance at speeds greater than 40 mph. In Phase I we will integrate high resolution imagery as well as atmospheric science instruments into the UAS and demonstrate a low cost approach to meeting Phase I NOAA objectives.
