about us <\/h4><\/div>\n\n\n\n

Since the emergence of large-scale LEO constellations, control and supervision of the radio spectrum have become strategic imperatives. The rapid proliferation of NGSO systems has significantly increased the density, granularity, and operational complexity of satellite-based communications. While these constellations provide global connectivity and enhanced resilience, they also introduce new challenges related to unauthorized usage, dual-use exploitation, and the potential misuse of commercial satellite infrastructure for illicit or hostile purposes.<\/p>\n\n\n\n

Traditional centralized monitoring architectures, originally designed for a limited number of satellites and continent-scale beams, are no longer adapted to the scale and structure of modern NGSO constellations. The proliferation of satellites, combined with the use of highly directional spot beams and aggressive frequency reuse schemes, dramatically increases the density and geographic fragmentation of radio emissions. The narrowness of these beams reduces the effectiveness of distant, centralized monitoring sites and complicates wide-area supervision. This new paradigm requires distributed, resilient, and autonomous monitoring capabilities capable of operating continuously and at scale. Effective spectrum supervision now depends on persistent and distributed visibility.<\/p>\n\n\n\n

In this context, Groundspace offers CelesGuard, a radio spectrum monitoring system built around a distributed network of autonomous sensors deployed at customer sites and equipped with electronically steerable antennas. Designed for scalability and operational resilience, the system enables real-time detection of unauthorized or anomalous activity, advanced pattern-of-life analysis, and regulatory compliance verification. CelesGuard provides satellite operators, regulators, and security stakeholders with persistent and sovereign visibility over spectrum usage.<\/p>\n\n\n\n

Complementing CelesGuard, Groundspace has developed WHISPR, a tactical system dedicated to the detection and geolocation of unauthorized NGSO terminals within a defined area of interest. In environments where NGSO terminals may be exploited for criminal activity, drug trafficking, maritime piracy, sanctions evasion, or other hostile operations, rapid identification and localization capabilities are critical. Available in both portable and platform-transportable configurations, with a range of up to 25 km, WHISPR enables the detection and geolocation of unauthorized terminals. It equips defense and security forces, authorities, and critical infrastructure operators with actionable situational awareness, supporting investigations, enforcement actions, and the protection of sensitive sites, borders, and maritime zones.<\/p>\n\n\n\n

Together, CelesGuard and WHISPR provide complementary strategic and tactical capabilities, enabling authorities to monitor, understand, and maintain dominance over NGSO-related spectrum activity across both national territory and operational theaters.<\/p>\n<\/div><\/div><\/div><\/div><\/div>\n\n\n\n
