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. Bejing-1 mission is regarded as the first of the next-generation DMC missions.
Additional Information The Beijing-1 microsatellite (formerly China DMC+4) is a cooperative Earth observation project of SSTL (Surrey Satellite Technology Ltd.), UK, and the Beijing LandView Mapping Information Technology Company Ltd (BLMIT) within the framework of DMC (Disaster Monitoring Constellation). The project is funded by the Chinese Ministry of Science & Technology, Beijing. It combines SSTL's standard Disaster Monitoring Constellation (DMC) multispectral camera with a high resolution panchromatic imager. BLMIT is a private company established to manage the commercial data distribution and services of Beijing-1. The project comprised also the installation in Beijing of a Mission Control Center, consisting of an S-band ground station and associated control systems, and the support to the customer payload data X-band ground station. 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.
