Constellr
German space company operating a thermal-infrared satellite constellation delivering defense-grade Land Surface Temperature intelligence.
Constellr operates a thermal-infrared Earth-observation satellite constellation delivering high-precision Land Surface Temperature data, originally for agricultural water monitoring and now advancing to defense-grade thermal intelligence for governments, militaries, and security agencies — including detecting naval activity, industrial operations, and critical-infrastructure behavior, notably at night when optical imagery is limited. Founded in 2020 by CEO Max Gulde, CTO Marius Bierdel, and CFO Christian Mittermaier, all former researchers at the Fraunhofer Institute for High-Speed Dynamics (Ernst-Mach-Institut) in Freiburg.
