Navigation

Navigation underpins nearly every mode of transportation, from aircraft flight paths to shipping lanes and autonomous systems. When GPS or GNSS is unavailable or compromised, operations can be delayed, rerouted, or even put at risk. 

Iridium PNT provides a trusted, independent signal that enables continuity of navigation services worldwide. With strong, resilient coverage from our crosslinked low-Earth orbit constellation of satellites, Iridium PNT keeps people, vehicles, and assets moving, across oceans, through cities, and in contested environments. 

Navigation failures can cascade into safety risks, service interruptions, and economic loss. Industries and governments depend on Iridium PNT to strengthen existing navigation systems and help ensure movement continues without interruption. 

• Aviation and Transportation. Pilots, air traffic controllers, and logistics providers rely on uninterrupted signals to maintain safe routes and schedules. 
• Maritime. Cargo and passenger vessels depend on resilient positioning and navigation when crossing oceans and optimizing routes. 
• Autonomous Systems. From drones to vehicles, reliable navigation data allows these systems to operate safely where GPS is blocked or jammed. 
• Governments. Mission-critical operations require dependable navigation even in environments where traditional systems fail. 

By complementing GPS/GNSS with independent, high-powered signals, Iridium PNT means navigation data is available when and where it matters most.  

Iridium PNT is already serving critical industries and organizations where navigation resilience is non-negotiable.  Maritime operators trust Iridium for global coverage in regions where GPS is unreliable. Governments depend on PNT signals to safeguard operations in contested environments. 

This proven adoption demonstrates Iridium PNT’s role as an operationally ready solution — strengthening navigation systems today while preparing industries for the challenges of tomorrow.
