DMC3: The Mission

DMC3: The Mission

Under a £110m contract SSTL designed and manufactured three SSTL-300S1 satellite platforms, a new smallsat design which provides unparalleled 1 metre high resolution imagery with high speed downlink and 45 degree off-pointing.

The three satellites formed a new constellation, TripleSat, with daily revisit times which is crucial for change detection, disaster monitoring and response planning, and essential for acquiring cloud-free imagery.

The SSTL-300S1 satellite design features advanced avionics and optical systems that make it possible to perform several different types of imaging such as mapping terrain, strip imaging and mosaic imaging for wide areas. 

Beijing-based commercial imaging company, 21AT, has leased 100% of the imaging capacity of the three satellites.
