Unseenlabs Scales Space Surveillance with New Microsatellite Fleet

The new satellite, designated BRO-31, represents a shift from the company’s previous 15-kilogram nanosatellite model to a more robust 150-kilogram platform. While the company retains its signature monosatellite architecture—where each unit functions independently—the upgraded hardware allows for the monitoring of a much wider spectrum of frequencies, including L, S, C, X, and Ku-bands. This expansion enables the tracking of dual-use signals for both civilian infrastructure and defense applications.

CEO Clément Galic stated that the technology unlocks new geolocation and characterization capabilities, moving the firm’s reach into complex geopolitical environments. With 23 satellites currently in orbit, the company is positioning this second generation to handle broader spectrum monitoring and interference detection. The integration of BRO-31, handled by German firm Exolaunch, signals a transition toward more intensive industrial-scale operations for the Rennes-based provider.
