GEOSAT Overview

Series Background

GEOSAT-1 was the first satellite of the second generation of the Disaster Monitoring Constellation (DMC). The DMC is an international programme of Low Earth Orbit satellites. Working together, the network has the capability to provide a daily global imaging capability for rapid-response disaster monitoring and mitigation.

GEOSAT-2 is the second satellite of the GEOSAT Earth Observation system, following GEOSAT-1. A high resolution satellite, it became the first European fully-private satellite capable of providing sub-metric multi-spectral imagery.
