The Aisa Eaglet combines high performance Hyperspectral Imaging and Exceptional compactness in a system particularly designed to meet space and weight limitations of UAVs and small piloted aircraft.

Aisa EAGLET acquired full. Contiguous VNIR hyperspectral data with a high spatial resolution of 1600 pixels and an excellent sensitivity even in low light conditions.








AisaEAGLETS's cost effectiveness make it an exceptional and versatile remote sensing tool for environmental, forestry, agricultural, security and defence applications. The only moving part of AisaEAGLET is the shutter, used for dark image calibration. Since the image data is captured without any moving arts, there is no distortion caused by mechanical inaccuracies of the sensor itself

The AisaEAGLET system has a total mass of 210 kg, including hyperspectral sensor, compact data acquisition computer and GPS/IMU init. The system’s modular design facilitates its installation in different payloads. Gilden Photonics provides support for the implementation of the sensor system control from the ground through a telemetric link in the UAV.

As well as other AISA sensors, AisaEAGLET can be easily used in ground based applications, using proprietary scanning devices that allow scanning of the target from a static platform like a tripod or security monitoring facility.
