BIRD (Bispectral and Infrared Remote Detection) is a satellite launched by ISRO in 2001 for DLR. This small (92 kg) boxlike system, with solar panels and two collectors on stub wings, has remarkable fire-detection qualities. It hosts a two-channel infrared sensor system in combination with a Wide-Angle Optoelectronic Stereo Scanner (WAOSS). It also features a neuronal network classificator in orbit to reduce downlink bandwidth and cost.[2]
The unique combination of a stereo camera and two infrared cameras gives the opportunity to acquire:
The attitude and control system of the BIRD satellite was reused in the TET-1 satellite.
