A new report from FrontierSI reveals accelerating global momentum in the emerging low-Earth orbit (LEO) positioning, navigation and timing (PNT) sector.

The second edition of the LEO PNT State of the Market study shows the number of identified initiatives rising from nine to 14 in just one year.

This reveals a shift in global navigation infrastructure, driven by increasing vulnerabilities in existing GNSS and the growing need for more resilient alternatives.

As incidents of GNSS jamming and spoofing continue to rise worldwide, industries increasingly require more resilient positioning and timing capabilities.

The report says that LEO-based systems are gaining attention as a complementary layer to GNSS, as they offer the potential for stronger signal resilience and improved performance in challenging environments.

No longer optional

In addition to dedicated LEO PNT systems, the study expands its scope to include signals of opportunity and fused SATCOM-PNT approaches, which leverage existing communication satellite constellations for positioning and timing.

These emerging paradigms demonstrate how navigation capabilities can be derived from opportunistic signal exploitation and integrated communication-navigation architectures, broadening the range of resilient PNT solutions beyond traditional GNSS frameworks.

The report also profiles major SATCOM providers and assesses their potential to deliver PNT services as part of their existing and future architecture.

“Reliable positioning and timing services underpin everything we do, from telecommunications to financial systems,” said Graeme Kernich, CEO of FrontierSI.

“This means building system resilience is no longer optional, and LEO PNT infrastructure plays an important part in offering alternatives.”

Early stages

The report reveals that while the number of dedicated LEO PNT initiatives continues to grow, the sector remains at an early stage of development.

As of the end of 2025, Iridium PNT remains the only fully operational commercial LEO PNT service, with most other initiatives progressing through pathfinder missions, early satellite deployments, or in-orbit validation activities.

“LEO PNT is still an emerging market, but the pace of activity is accelerating,” said Eldar Rubinov, PNT Lead at FrontierSI.

“By tracking the evolution of these initiatives each year, this report gives policymakers, industry and investors the insight needed to make informed decisions in a fast-moving and uncertain market.”

As the sector evolves, coordination across governments, industry and research will be critical to ensure LEO PNT develops as a viable, interoperable and trusted complement to GNSS.
