Problem
Traditional GNSS signals are weak, vulnerable to jamming, spoofing, ionospheric disturbances, and provide limited indoor and high‑latitude coverage, making them unreliable for defense, aviation, emergency services, and autonomous systems that require robust positioning, navigation, and timing.
Solution
Sharpnav offers a European sovereign low‑Earth‑orbit (LEO) PNT constellation that operates at approximately 1,000 km altitude, delivering signals up to 100 times stronger than conventional GNSS. The LEO architecture ensures faster signal acquisition and higher accuracy in dense urban areas, polar regions, and environments with high electromagnetic interference. Encrypted, redundant transmissions protect against jamming and spoofing, maintaining service continuity under electronic‑warfare conditions. The system is designed to interoperate with existing GNSS receivers, providing an additional resilient layer without requiring new hardware. Deployment will progress from a Nordic pilot of 4–6 satellites to a full global network of up to 300 satellites.
Target Audience
Primary customers are defense agencies, civil aviation operators, emergency response organizations, and developers of autonomous vehicles that require secure, high‑accuracy PNT services.
