The second generation DMC satellites carry the upgraded 22m gsd SLIM-6 sensor, which provides twice the pixel density per hectare of the first generation DMC 32m gsd sensors. The SSTL built satellites carry the latest technology advances, providing improved image quality, resolution and capacity with new sensors, purpose built optics, enhanced on board data storage, and high capacity X-band downlink.
The satellites are capable of providing very large area coverage with a twenty-fold capacity increase over the first DMC generation.
The sensor Linear push-broom sensor built by SSTL Optics Group to acquire a 650km swath with 22m ground sample distance (nadir).
