ACCESS MISSION DATA

The Disaster Monitoring Constellation (DMC) is a constellation of microsatellites formerly coordinated by DMCii to provide frequent observations of the Earth for monitoring natural disasters.

About DMC First Generation

The Disaster Monitoring Constellation (DMC) is a constellation of microsatellites formerly coordinated by DMCii to provide frequent observations of the Earth for monitoring natural disasters. The satellites were designed and built by Surrey Satellite Technology Ltd (SSTL). Each satellite was independently owned and controlled by a DMC consortium member.

Launched between 2002 and 2005, most of the satellites in the first generation have successfully concluded operations with only one satellite still operational.

The DMC constellation is part of ESA's Third Party Missions programme, in which ESA have an agreement to distribute data products from a number of the missions.

DMC First Generation Objectives

The aim of the Disaster Monitoring Constellation is to provide high resolution imagery from any part of the globe with daily revisit, with a particular focus on disaster monitoring.

DMC First Generation Instruments

The primary DMC 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.
