Key Takeaways
- Constellr offers defense-grade thermal intelligence, revolutionizing access to high-resolution thermal images.
- The start-up’s microsatellites reduce costs to 1-2% of conventional thermal missions.
- Constellr plans to launch a next-generation satellite providing <5 meter resolution by 2028.
Innovative Thermal Satellite Technology
Constellr, a Munich-based start-up, is transforming the accessibility of high-resolution thermal imaging, which can detect critical information such as forest fires and military targets before they become visible. Traditionally, such data has been confined to government agencies, but Constellr is changing this narrative.
The company, co-founded by Marius Bierdel, aims to provide advanced thermal imaging solutions through miniature satellites. These microsatellites, weighing just 115 kilograms and about the size of a washing machine, contain high-precision thermal sensors that measure infrared radiation, allowing for detailed assessments of various situations from agricultural stress to military activities.
CEO Max Gulde highlights that Constellr’s operational costs are just 1-2% of those for conventional thermal satellite missions that typically require massive budgets and extensive resources. The idea for Constellr began in 2017 during Gulde and Bierdel’s tenure at the Fraunhofer Institute for High-Speed Dynamics. They faced a challenging beginning, submitting 14 unsuccessful grant applications, yet they persevered. In 2020, they launched Constellr alongside co-founder Christian Mittermaier.
The company’s satellites deliver daily temperature data with a resolution of 30 meters, and a more advanced generation is in the works, aimed for a precision of below 5 meters. Constellr plans to expand its satellite constellation to allow for data capture over any location on Earth every 30 minutes by 2032.
Serving various sectors, Constellr caters to government and military clients, as well as agricultural and energy enterprises, providing vital intelligence based on its thermal data. Since its inception, the company has raised €75 million in funding, with a notable €37 million Series A round completed in February 2026. This funding affirms Constellr’s status as a leading entity in Europe’s expanding New Space sector.
Moreover, Rainer Müller of Germany Trade & Invest (GTAI) notes that Germany stands at the forefront of the New Space initiative in Europe, thanks to significant governmental investment in space technology, both for civilian and military purposes. Recently, Constellr moved its headquarters to Munich, closer to major aerospace and defense companies, securing a strategic position in the industry. With additional offices in Berlin, Toulouse, and the U.S., Constellr is poised for both national and international growth, leveraging Germany’s burgeoning space technology landscape.
