A New Channel For SPOT Satellite In The SWIR Band

On SPOT 4, of the second generation earth observation satellite, will be implemented a SWIR channel in the 1.55/1.70 μm wavelength. A new GaInAs/InP detector has been developed for this purpose. This document describes the new instrument with emphasis on focal plane assembly, then technology and specifications of the new detectors of 3 000 elements.
