The Disaster Monitoring Constellation 1st generation (DMC-1) is a constellation of microsatellites coordinated by DMCii to provide frequent observations of the Earth for monitoring natural disasters. The satellites are designed and built by Surrey Satellite Technology Ltd (SSTL) and each satellite is independently owned and controlled by a DMC Consortium member.

The constellation operates in a low Earth orbit. Each satellite is phased at 90° to the next to enable a daily revisit of a point target on the Earth's surface.

The DMC-1 satellites operate in the visible to near-infra-red part of the spectrum, which makes them very useful for crop and forest monitoring as well as general Earth observation. DMC-1 imagery is also used to augment data acquired from the Landsat series of satellites.

The primary DMC-1 imaging payload is the SLIM-6 class imager. The design of this sensor provides a three spectral band, nadir pointing imager capable of providing high and mid-resolution images of the Earth's surface when operating in a sun-synchronous low Earth orbit.

The SLIM-6 imager is composed of two banks, each bank consisting of 3 channels (NIR, Red, Green spectral bands). The two imager banks are mounted at an angle to provide a total imaging swath of over 600 km and an overlap between the simultaneously acquired images.

Spectral band description Spectral bandwidth GSD at nadir Equivalent Landsat 7 ETM+ Spectral Channel
NIR 0.77 – 0.90 μm 31.822 m ETM+4
RED 0.63 – 0.69 μm 31.822 m ETM+3
GREEN 0.52 – 0.60 μm 31.822 m ETM+2

Icebergs A-68 and B-46 in Antarctica

Proba-V data was used to track the evolution of the A-68 and B-46 icebergs in the Antarctic Sea. The large icebergs broke off from the Larsen C ice shelf and Pine Island Glacier, respectively, in 2017 and 2018.
