Science Payload

The science payload is the Tau 2 640 Longwave Infrared Camera, which is an uncooled microbolometer developed by FLIR Technologies. The camera offers a 640 x 512 pixel resolution, and a 6.2° x 5.0° field of view, which correlates to a ground footprint of 43.5 km x 35 km at an altitude of 400 km. A lens of 100 m/pixel has been selected in order to provide an angular resolution up to 68m/pixel to clearly define the smallest Local Climate Zone, within the selected areas of the city. One image will be taken during each pass over a city. Slewing conducted by the ADCS system during imaging will be used to mitigate image blur. Due to time constraints, the camera was not filtered and will operate in the wavelength of 7μm-14μm.
