SharpNav LEO-PNT constellation

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.

Traditional GNSS faces several key issues - making it unreliable in demanding environments

Operational impact on defence operations & exercises, corrercial aviation, and daily life in Europe → requires non-GNSS-dependent PNT layer

Jamming

Due to the low power of GNSS, even small jamming devices can overpower the satellite signals, leading to complete signal loss

Spoofing

Malicious operators can broadcast counterfeit signals to trick civilian receivers into using false position or timing data due to GNSS's lack of encryption

Natural interference

Ionospheric effects such as signal bending and solar activity can negatively affect the signal - particularly in polar regions

Limited indoor penetration

Urban environments and enclosed spaces suffer from weak and inaccurate GNSS signal

Legacy systems are not designed for the future needs of PNT

GNSS cannot answer the modern demand for reliability, security, accuracy and fast signal connectivity

“EASA and IATA reported that GPS signal losses increased globally by 220% between 2021 and 2024”

“There were around 7 500 reports about GPS disruptions in 2023, compared to around 1 500 in 2022”

“As NATO forces conducted training exercises, GPS spoofing, potentially by Russia, complicated the operation”

“Russian signal interference—specifically GPS jamming and spoofing—disrupted around 123,000 flights in the Baltic-Nordic region from January to April 2025”
