- SSTL has developed the BEIJING-1 microsatellite bus for the Beijing Landview Mapping Information Technology Ltd (BLMIT). The BEIJING-1 enhanced microsatellite is an Earth observation spacecraft that combines SSTLs 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 32m multispectral imager currently flown on AlSAT-1, UK-DMC and NigeriaSat-1, plus a new 4m 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. BEIJING-1 is supported by SSTL S-band telemetry, telecommand and an 8Mbps data retrieval ground station and is further supported by a customer furnished X-band data retrieval ground station and reflector subsystem. The Satellite was Launched on October 27th 2005 following a 24-month spacecraft development programme and is presently undergoing in orbit commissioning.
