Sensors and Systems Development

The payload bays of NASA’s high-altitude Global Hawk environmental science aircraft are jammed with 11 specialized science instruments during checkout operations for the Airborne Tropical Tropopause Experiment (ATTREX), a multi-year airborne science campaign to probe unexplored regions of the upper atmosphere for answers to how changes in a warming climate is changing Earth.

The Sensors and Systems Development branch is part of the Research and Engineering Directorate at NASA’s Armstrong Flight Research Center in Edwards, California. The branch consists of two focused groups: Research Avionic Systems Development and Sensor and Technology Research and Development. The branch is responsible for the mission avionic systems development for flight and/or ground tests (in hardware and software areas), new technology, and new sensing technique research and development. This talented engineering staff has profound experience and expertise in designing, developing, and programming for research mission/aircraft systems, including selecting, fabricating, qualifying, integrating, installing, and testing flight-worthy hardware. The branch works closely with Armstrong’s Vehicle Integration and Instrumentation branch to integrate developed systems onto aircraft to serve flight projects’ purposes. Through systems engineering roles and responsibilities, branch personnel also support science campaigns on platforms like the C-20A Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) and aeronautics research projects like supersonic schlieren imaging, autonomy, electric propulsion, and many others.
