About
ThothX Meridian specializes in Space Situational Awareness, providing 24/7, all weather, high precision, near real-time information on objects in GEO orbits. Leveraging over mature radar technology, ThothX Meridian is part of the ThothX Group and its Global Strategy to reach complete coverage of the GEO belt.
The proprietary radar system – Earthfence – is capable of observing Resident Space Objects up to 100,000 Km in range, providing meter-scale range accuracy with industry-leading latency (<2 min) and cadence (≤30 s), as well as discriminating objects down to 60 meters apart.
These capabilities serve both civil and defence needs, from safeguarding space assets to ensuring the resilience of critical space infrastructure against emerging risks (e.g. collision, interference and espionage). The technology’s dual-use nature has ensured the inclusion of ThothX Meridian in the 2025 cohort of NATO’s DIANA Accelerator Program.
