This SBIR Phase I project will develop the Flight System Monitor which will use non-intrusive electrical monitoring (NEMO). The electronic system health of components and systems will be measured and tracked by carefully monitoring and analyzing of power usage and start up and shut down transients. In depth analysis of this data enables real time assessment of system and component functioning and identifies potential system and component faults and failutes. The system is light weight, small and inexpensive because the system requires only a sensor at the mains power input and uses existing power wiring to carry data. Phase I will involve ground measurements on the control and power systems of a small UAV. Phase II will involve measurements and analysis of a system in flight.
