The DMC3/TripleSat Constellation in the Orbit

Press_Release_DMC3_successful_launch_21AT.pdf

Mme Wu Shuang, CEO & President of 21AT, said: ¡°I am very glad that the three satellites are in orbit and have started communication with the ground station. It is the first step of our long march and we are looking forward to the commencement of our BJII data services following the completion of the commissioning of the DMC3/TripleSat Constellation.¡±

The Twenty First Century Aerospace Technology Co., Ltd. (21AT), a commercial Earth observation satellite operator based in Beijing, has bought the imaging capacity of three DMC3/TripleSat satellites that were designed and manufactured by SSTL. The very high-resolution imager on board the satellites will provide 1 metre ground sampling distance (GSD) in panchromatic mode, and 4 metre GSD in multispectral mode, with a swath width of 23.4km.  

The three satellites will be phased 120 degrees apart around the same orbit using their on board propulsion systems within three months after the launch; thus with off-pointing capability, the DMC3/TripleSat Constellation will be able to target anywhere on Earth once per day. In addition, the wide swath width of the satellites provides the best combination of spatial resolution and time resolution ¨C aiming at stimulating operational monitoring applications, such as urban planning and intelligent management, based on changes detected by timely and regular cloud-free, very high-resolution imagery.

About 21AT
Twenty First Century Aerospace Technology Co., Ltd. is the first and only EO commercial satellite operator in China. Its headquarters is in Beijing, employs more than 300 employees and has been providing remote sensing applications in China since the launch of its first satellite ¨C Beijing-1 in 2005. Beijing-1 is one of five satellites in DMC that had provided international disaster response through International Charter and Beijing-1 satellite imagery to international customers. Based on Beijing-1 success, 21AT has acquired the new capability of three 1m satellites in a constellation for BJII service. In orbit commission is expected to be completed three months after the launch. 21AT will start the operational worldwide satellite data services from the DMC3/TripleSat Constellation following the completion of the commission. 21AT will create new applications for customers and business opportunities for worldwide partners through its operational monitoring services powered by DMC3/TripleSat Constellation.
