Constellr

Constellr is headquartered in Freiburg, Germany, with additional offices in Berlin and Munich. The company builds and operates a constellation of satellites carrying high-precision thermal infrared sensors, creating what it calls a "thermal intelligence atlas" of the planet — data that reveals information invisible to optical and radar sensors.

Constellr's satellites measure absolute surface temperature to within 1.0–1.5 K accuracy, with a temperature sensitivity (NETD) of 0.05–0.15 K and native ground resolution of 30 meters (27.3 m GSD from a 510 km orbit). This lets analysts detect hidden activity such as heat sources and anomalies, track behavior and usage patterns over time through day-night cycles, verify the operational status of assets and infrastructure, and identify emerging risks like overheating or load imbalance before they become visible through other means.

The company's technology roadmap spans current capability, near-term missions, and future constellation expansion, with a ground segment and analytics platform processing the thermal data into actionable intelligence. Constellr's customers and partners include GAF AG, JSAT International, and programs connected to the EU's Copernicus Earth observation initiative, and the company has exhibited at major industry events including ILA Berlin.
