DLR small satellite onBi-spectral Infrared Detection (BIRD) observed Sydney wildfires 4 and 5 ofJanuary 2002
TheGerman Aerospace Center (DLR) Bi-spectral InfraredDetection (BIRD) smallsatellite is a technology demonstrator of new infrared push-broom sensorsdedicated to recognition and quantitative characterisation of thermal processeson the Earth surface. BIRD was successfullypiggy-back launched on 22 October 2001 with an Indian Polar Satellite LaunchVehicle (PSLV-C3) into a circular sun-synchronous orbit with an altitude of 572km and a North South local equator crossing time at 10:30 h. BIRD is a currently running in its commissioningphase. The BIRD main sensor payload consists of:
a two-channelinfrared Hot Spot Recognition Sensor system (HSRS),
a Wide-AngleOptoelectronic Stereo Scanner (WAOSS-B).
Their characteristics are given in the table below.
The BIRD main payload wasswitched on over the East coast of Australia on January 4 and 5, 2002 to observethe wildfires in that region by the Hot Spot Recognition System (HSRS) which isdedicated to fire detection and analysis. The ability of the BIRD HSRS to perform a second exposure within the samplinginterval makes it possible along with measuring small thermal contrasts also toimage hot targets without saturation.
