Family DMC (Disaster Monitoring Constellation)

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 microsatellites. The DMC consortium comprises a partnership between organizations in Algeria, China, Nigeria, Turkey and the United Kingdom.

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.
