ALSAT-1 was Algeria's first national satellite and was designed and constructed by SSTL within a collaborative programme with the Algerian Centre National des Techniques Spatiales (CNTS).
ALSAT-1 carried Earth imaging cameras which provided 32-meters resolution imaging in 3 spectral bands (NIR, red, green) with an extremely wide imaging swath of 600 km. ALSAT-1 was the first satellite in the Disaster Monitoring Constellation.
