The National Space Program (PSN) horizons 2020 planned to put in place space infrastructures, space systems and increase the specialized human resources in space technologies. Among the space systems planned in the PSN are Algeria's satellites (Alsat-2A, Alsat -2b, Alsat -3, Alsat -4, African Resource Management ARM and the communications satellite Alcomsat-1), of which a significant number should be partly or totally integrated in the Algerian center for satellite development "CDS". CDS offers the technological environment for national competence to develop the future Algerian satellite systems. Algeria's objectives is to make of space tools a powerful instrument in national prosperity in the fields of earth observation, meteorology and communications. CDS comprises: A satellite integration hall: a clean room of 27 meters x 11 meters A satellite environmental tests building. Rooms and equipment for the components storage, cleaning, inspection, assembly and integration equipment, etc. Alsat-2 S-Band antenna system and control ground segments. Alsat-1B S/X Band antenna system and control ground segments. The CDS is organized in 6 departments: Space systems and missions. Satellite engineering Satellites AIT Environment testing Quality and process Research on space technology Those departments house mechanical & thermal, electrical, electronic and optics research and development laboratories. The satellite integration building consists of a large clean room of class 100000, with 4 subareas dedicated to: satellite integration. satellite subsystems assembly. solar systems integration subarea for optical integration / alignment, class 100 on a seismic bloc. Those areas are separated by sliding curtains. The satellite environmental tests building is also planned for the future, this building shall consist of: anechoic chamber for EMC tests thermal vacuum chamber vibration test chamber acoustic test chamber Missions: development of satellites (up to 1000 kg) integration of space subsystems and solar panels (class 100.
