Airborne Hyperspectral Imaging
Galileo uses state-of-art AISA hyperspectral sensors which are second to none in delivering high spectral and spatial resolution data in the VNIR (400-1000 nm) and/or SWIR (1000-2500 nm) spectral range.
To accommodate a range of selectable targeting, the collection parameters are software programmable (pre-flight and in-flight), based upon the spectral/spatial resolution parameters sought by the operator to attain mission requirements.
The sensor are radiometrically calibrated to a NIST traceable radiance source.
The imaging system also consists of a high precision IMU/GPS unit and a ruggedized flight computer equipped with professional imaging software, thus all collected raw data can be rapidly collected and easily radiometrically and geometrically calibrated for further analysis.
Proprietary algorithms have been developed and proven by Galileo to facilitate data processing and analysis. The result is a cost effective, end-to-end, airborne collection capability that acquires research grade spectral imaging data for use in military and commercial remote sensing programs.
Additional Equipment

AISA Eagle Hyperspectral Imaging Sensor
The AISA Eagle is a high-performance hyperspectral imaging system operated by Galileo Group, providing a cost effective, end-to-end, airborne collection capability that acquires research grade spectral imaging data for use in military, environmental and commercial remote sensing programs.
The system has been used in a number of operational scenarios, domestically and abroad, where it has achieved solid success in detecting and discriminating low-observable targets.
The sensor operates across the VIS/NIR portion of the spectrum (400-1,000 nm), resolving spectral differences as fine as 2-5 nm. With around 1,000 pixels per scanning line, the system is able to image at sub-meter resolution.
