China-DMC+4 (Beijing 1)

China-DMC+4 [SSTL]

SSTL has developed the China DMC+4 microsatellite, renamed Beijing 1 after launch, for the Beijing Landview Mapping Information Technology Ltd (BLMIT). The China DMC+4 enhanced microsatellite is an Earth observation spacecraft that combines SSTL's standard Disaster Monitoring Constellation (DMC) multispectral camera with a high resolution panchromatic imager.

The customised microsatellite has specific enhancements to provide accommodation for the two imagers: a 32 m multispectral imager currently flown on AlSAT-1, UK-DMC and NigeriaSat-1, plus a new 4 m panchromatic imager developed under contract to SIRA Electro-Optics Ltd. The satellite bus provides highly agile attitude control to provide accurate pointing and the knowledge necessary for the mapping requirements of the mission.

China-DMC +4 was launched in October 2005 onboard a Kosmos-3M launch vehicle from the Plesetsk Cosmodrome following a 24-month spacecraft development programme.
