Purpose The Disaster Monitoring Constellation (DMC) is an international program initially proposed in 1996 and led by SSTL (Surrey Satellite Technology Ltd), Surrey, UK, to construct a network of five affordable LEO micro-satellites. The objective is to provide a daily global imaging capability at medium resolution (30-40 m), in 3-4 spectral bands, for rapid-response disaster monitoring and mitigation.
Applications Forestry, Agriculture, Emergency and Disasters, Land Cover Mapping

Lineage The DMC concept arose from the recommendations of the United Nations UniSpace-III conference in July 1999 (Vienna, Austria), which recommended that space agencies should seek ways of coordinating activities in space to better monitor natural disasters, and provide information for disaster relief response planning. SSTL worked to build a coordinated constellation that could achieve the goal of daily repeat imaging anywhere in the world. To do this it had to convince a group of international clients to each purchase a DMC satellite and to agree to work together in a phased orbit. The credibility of the program was greatly enhanced by the support from the British National Space Centre (BNSC) which awarded a MOSAIC grant that enabled SSTL to build a UK satellite. The extraordinary project to bring many nations together to create a working constellation in space has been a huge success. New satellites with enhanced capabilities are being added as the first ones reach the end of life, and new members are joining.
Additional Information AlSAT-1 is a micro-satellite of Algeria, the first of five micro-satellites launched into the DMC (Disaster Monitoring Constellation) in a time period from 2002-2005. A team of 11 Algerian engineers from CNTS (Centre National des Techniques Spatiales) were trained at SSTL throughout the AlSAT-1 project period. The AlSAT-1 spacecraft is being funded by the Algerian government and has been built by SSTL as part of a know how transfer program. The DMC consortium comprises a partnership between organizations in Algeria, China, Nigeria, Turkey and the United Kingdom. Along with SSTL, each organization has built an advanced yet low-cost Earth observation micro-satellite to form the first ever constellation specifically designed and dedicated to monitoring natural and man-made disasters.
