Design, Development and First Assessment of the SWIR Instrument for Remote Sensing on Board of Egypts at-1
Abstract
Egyptsat-1 is the first remote sensing satellite of Egypt, developed by the Ukrainian companies Yuzhnoye (spacecraft) and CONECS (payload) on behalf of the Egyptian government. The satellite was launched on April, 17th, 2007 from the cosmodrome Baikonour as the prime payload on a Dnepr launcher. The IREI - Infrared Earth imager instrument is equipped with a refractive optic with a 430 mm focal length and a 1:4.4 aperture. The obtained swath width and Nadir looking ground pixel resolution are 55 km and 39*46 m, respectively. The signal to noise ratio of the overall instrument is better than 100:1, while the MTF is better than 35% at the Nyquist limit In order to realize a focal plane with 1500 pixels, 3 InGaAs with 500 pixels each are optically butted in the Image plane of the instrument
