Sharpnav's LEO PNT constellation is a next-generation satellite navigation system that surpasses traditional GNSS by operating in low Earth orbit (~1,000 km) instead of medium orbit (~20,000 km). This design delivers up to 100x stronger signals and ensures high-accuracy positioning even in dense cities, polar regions, and interference-prone areas.
Built for resilience and security, Sharpnav employs encrypted, redundant signals to counter jamming and spoofing, maintaining reliability under electronic warfare conditions. Its polar orbits provide full coverage in high-latitude regions like the Nordic and Arctic zones.
The system will launch in phases—starting with a Nordic pilot of 4-6 satellites, expanding to 50 for regional and eventually 300 for global coverage—and remains compatible with existing GNSS systems. Sharpnav aims to redefine positioning, navigation, and timing (PNT) for defense, aviation, emergency, and autonomous applications worldwide.
Operational impact on defence operations & exercises, corrercial aviation, and daily life in Europe → requires non-GNSS-dependent PNT layer
Due to the low power of GNSS, even small jamming devices can overpower the satellite signals, leading to complete signal loss
Malicious operators can broadcast counterfeit signals to trick civilian receivers into using false position or timing data due to GNSS's lack of encryption
Ionospheric effects such as signal bending and solar activity can negatively affect the signal - particularly in polar regions
Urban environments and enclosed spaces suffer from weak and inaccurate GNSS signal
GNSS cannot answer the modern demand for reliability, security, accuracy and fast signal connectivity
