Objectives and Applications
HEO is a constellation of 25 satellites designed to monitor climate-related changes such as soil erosion, deforestation, and ice melt in near real time, and to support early warnings for natural hazards including floods, avalanches, and earthquakes.
It is part of the IRIDE programme, which represents an end-to-end system, consisting of sub-constellations of Low Earth Orbit (LEO) satellites (upstream segment), ground-based operational infrastructure (downstream segment), and services tailored for the Italian Public Administration (service segment).
