Greece becomes first country to use dedicated satellite network to detect wildfires

Greece has become the first nation in the world to integrate a dedicated satellite constellation into its national firefighting system. Four nanosatellites, each smaller than carry-on luggage, were launched into low orbit in May 2026 by German company OroraTech. The satellites carry thermal sensors capable of detecting new blazes as small as four meters across, far smaller than what traditional satellites can spot.

AI models filter out false alarms from sources like solar panels and sunbaked rock faces, then send processed alerts with location, size, and intensity data directly to fire commanders. This allows responders to prioritize action when multiple fires ignite simultaneously. The system fills critical coverage gaps in remote terrain and is especially valuable during Greece's increasingly severe wildfire seasons, which have been worsened by rising global temperatures.

The 200 million euro system is EU-funded and part of a broader European consortium combining thermal, radar, and optical satellites. The initiative reflects Europe's push for technological sovereignty in climate monitoring and disaster response, with future applications planned for border surveillance, crop management, and urban heat island mapping. For earth observation practitioners, this deployment marks a significant milestone in operational use of small satellite constellations for real-time environmental monitoring and public safety.
