This Startup Successfully Detects Wildfires in Minutes Using Thermal Satellites and AI
Summer has become a season of danger. Every year, megafires devastate thousands of hectares around the Mediterranean, and traditional detection systems arrive too late. But a young German startup, OroraTech, has taken on a seemingly impossible challenge: spotting a fire from space in under ten minutes and alerting firefighters before the blaze spirals out of control.
Founded in 2018 in Munich by a team of space engineers and artificial intelligence specialists, OroraTech grew up in the shadow of aerospace giants. Yet it has convinced Greek rescue services, international insurers, and even the European Space Agency (ESA) to bet on its technology. Their wager? Using shoebox‑sized nanosatellites to track hotspots 24/7, through clouds and smoke.
A Race Against Time to Save Lives
The problem with current public satellites — such as NASA's or the Copernicus program's — is latency. They pass over an area every few hours, and data often takes over an hour to reach ground teams. Meanwhile, a small spark can turn into a wall of flames.
OroraTech has flipped this logic. Its FOREST satellites overfly every point on Earth multiple times a day — 96 daily passes by 2028, meaning an image every 15 minutes. Even better, thanks to an onboard GPU, the artificial intelligence processes data directly in space. It only sends suspicious zones back to ground stations — in just minutes.
During a 2023 demonstration, the startup sent an alert in just three minutes after overflight. A record that public systems cannot match. Today, their goal is to keep the entire chain — overflight, analysis, notification — under ten minutes.
Real Impact for Firefighters and Forest Managers
For fire services, every minute saved means hectares spared and lives protected. OroraTech quantifies the benefit: up to 97% reduction in detection costs and about $1 million in avoided damage when a fire is kept under 50 hectares.
But the startup doesn't stop there. Its Wildfire Solution platform turns raw data into interactive maps, geolocated alerts, and automated reports. Firefighters can see hotspot evolution in real time, anticipate spread directions, and coordinate their response with unprecedented precision.
Where Is OroraTech Already Operational?
The startup has already won clients in 25 countries, but its technology is most deployed in Greece. The Hellenic Fire System, developed with ESA, uses a small FOREST constellation and a ground station to monitor the entire Greek territory in near‑real time. Results are so promising that other Mediterranean countries — Spain and Italy — are now negotiating partnerships.
Beyond wildfires, OroraTech is now applying its know‑how to other fields: urban heat island detection, agricultural monitoring, oil spill surveillance… The same thermal intelligence, serving a more resilient planet.
❓ What You Need to Know About Space‑Based Fire Detection
Which satellites are used for thermal detection?
The main ones are polar‑orbiting satellites (MODIS, VIIRS) and geostationary ones (SEVIRI, FCI). But OroraTech developed its own FOREST constellation, specifically designed for fast fire detection with far better resolution and frequency.
What is the resolution of OroraTech's sensors?
The SAFIRE cameras on FOREST CubeSats offer ground resolution of around a dozen metres, allowing them to spot a single burning tree — much finer than public sensors which often cap at 375 m or 1 km.
What are the limitations of this technology?
Cloud cover or very thick smoke can still hamper thermal sensors. Also, very small fires or those under dense forest canopy are harder to detect. OroraTech's AI is specifically trained to minimise such false negatives.
How are alerts transmitted to firefighters?
The Wildfire Solution platform sends alerts via email, SMS, REST API, or directly into the emergency services' crisis management systems. Teams receive a map, precise location, and estimated fire intensity.
