Alsat 1B is an Algerian medium resolution earth observation satellite built jointly by the Algerian Space Agency (ASAL) and Surrey Satellite Technology Ltd (SSTL).

Alsat-1B is based on the SSTL-100 platform, hosting a 24 m multispectral imager and a 12 m panchromatic imager.

The contract was signed in July 2014. Eighteen ASAL engineers will undertake the Assembly, Integration and Test phase of the satellite in Algeria, offering further opportunities for the transfer of skills and the development of local capabilities. Eighteen Algerian students will also study for Higher Degrees at the University of Surrey based in Guildford.
