The AlSat-1B satellite was launched into orbit on September 26, 2016 from the Satish Dhawan Space Centre in Sriharikota, India. It was developed by the Algerian Space Agency (ASAL) in corporation with Surrey Satellite Technology Ltd (SSTL). The AlSat-1B satellite orbits at 670 km above the earth's surface and carries a 24m multispectral imager and a 12m panchromatic imager delivering images with a swath width of 140km.  The satellite carries two High Speed Data Recorders and two Flash Mass Memory Units capable of recording, managing and storing image data for high speed downlink via S-Band and X-Band transmitters. The data collected by AlSat-1B helps monitor climatological disasters (forest fires, glacial lake outbursts, droughts) and hydrological disasters (landslides and floods).
