Positioning

Precise location is the foundation of modern infrastructure. Aviation, shipping, transportation, autonomous systems, railways and emergency responders all depend on accurate positioning to operate safely and efficiently. Yet GPS/GNSS signals can be blocked, jammed, or spoofed—especially indoors, in urban canyons, or in contested environments. 

Iridium PNT provides resilient, high-powered signals from our crosslinked low-Earth orbit constellation, delivering reliable positioning data everywhere on Earth. Whether inside a data center, navigating through a dense city, or tracking assets across oceans, Iridium PNT means organizations will know where they are. 

Iridium PNT has been independently validated by the National Institute of Standards and Technology (NIST) as a reliable source of location data. NIST’s testing confirmed that Iridium PNT delivers highly accurate positioning information, even in environments where GPS/GNSS cannot reach. 

This validation underscores Iridium PNT as more than a complementary service. It is a trusted, standards-recognized layer of positioning resilience, capable of supporting mission-critical infrastructure, national defense, and commercial operations worldwide. 

Precise location data is the invisible backbone of the global economy and national security. Consider the impact across sectors: 

• Transportation. Freight depends on reliable coordinates for safe navigation across land and sea. 

• Finance. Global markets require accurate location and timing to validate trades and transactions. 

• Telecommunications. Networks and towers must be precisely located to align with coverage footprints and support 5G rollouts. 

• Government. Positioning data is vital for situational awareness, logistics, and protecting national infrastructure. 

Without resilient location data, disruptions cascade into safety risks, outages, and financial instability. Iridium PNT helps ensure continuity no matter the environment.
