Airborne Thematic Thermal InfraRed and Electro-Optical Imaging System

The innovation is an advanced Airborne Thematic Thermal InfraRed and Electro-Optical Imaging System (ATTIREOIS). ATTIREOIS sensor payload consists of two sets of advanced Focal Plane Arrays (FPAs)Â? a broadband Thermal InfraRed Sensor (TIRS) and a four (4) band Multispectral Electro-Optical Sensor (MEOS) to approximate Landsat ETM+ bands 1,2,3,4, and 6, and LDCM bands 2,3,4,5, and 10+11. The airborne TIRS is 3-axis stabilized system capable of providing 3D photogrammetric images witha 1,850 pixel swathwidth via pushbroom operation. MEOS has a total of 116 million simultaneous sensor counts capable of providing 3 cm spatial resolution multispectral orthophotos for continuous airborne mapping. ATTIREOIS is a complete standalone and easy-to-use portable imaging instrument for light aerial vehicle deployment. Its miniaturized backend data system operates all ATTIREOIS sensor components, an INS/GPS, and an e-Gimbal Control Electronic Unit (ECU) with a data throughput of 300 Megabytes/sec. It has a volume of 0.03 m3 and a mass of 20 kg. The backend provides advanced onboard processing, performing autonomous raw sensor imagery development, TIRS image track-recovery reconstruction, LWIR/VNIR multi-band co-registration, and photogrammetric image processing. With proposed geometric optics and boresight calibrations, the ATTIREOIS data products are directly georeferenced withan accuracy of approximately one meter.
