Abstract: A system for airborne detection of fires and transmission of fire location and characteristic data to the system ground station. The system includes an airborne pod and an associated ground station. The pod uses a passive infrared (IR) scanning system which employs a rotating and nutating mirror within an air slipstream driven propeller/spinner and is optically coupled to an infrared detector. A computer in the pod receives fire pod GPS position, IR detector fire spot detection pulse or ‘hit’ plus fire spot characteristics, spinner/mirror rotation and nutation angle at the ‘hit’ time and pod platform attitude relative to North-East-down using an on board Inertial Measurement Unit (IMU). The computer then calculates the firespot GPS location, and processes associated firespot characteristic data and downlinks this data to the ground station. Onboard pod video scene cameras also provide operational video that is also downlinked to the ground station.
