Attention:
Please note that operation of the AISA Eagle hyperspectral camera requires experienced scientific staff on board the aircraft.
Summary
AISA Eagle is a system for VNIR hyperspectral imaging. It acquires full, high quality hyperspectral data with 1000 swath pixels and high image rates. AISA Eagle is a complete, pushbroom system that consists of a compact hyperspectral sensor head, GPS/INS sensor, and data acquisition unit in a rugged PC. An additional Fiber-Optic Downwelling Irradiance Sensor (FODIS) simultaneously aquires data of incoming radiation.
