Accurate Timing: The Hidden Backbone of Modern Life

Financial networks, mobile carriers, energy grids, and transportation systems all rely on precise timing synchronization to function. Without it, trades fail, calls drop, power grids destabilize, and transportation networks lose critical coordination.

Iridium® PNT delivers a trusted, independent source of time. With a resilient signal from our crosslinked low-Earth orbit constellation, Iridium PNT keeps systems synchronized indoors, in dense cities, and across the most remote regions.  

Available today, Iridium PNT is built for industries and organizations that can’t afford downtime. 

Precise Timing is Invisible but Essential

Timekeeping is not just about knowing the hour of the day. It’s about ensuring that every part of our connected world moves in lockstep.  

A fraction of a second can determine whether financial markets run smoothly, whether a 5G call connects, or whether freight reaches its destination on time. When GPS is disrupted — whether by interference, jamming, or urban obstructions — these systems lose their sync. 

Iridium PNT helps ensure critical industries stay aligned: 

  • Finance. Global markets depend on precise timestamps to validate billions of transactions each day.
  • Telecommunications. Mobile and 5G networks must be synchronized down to microseconds to function properly.
  • Energy and Utilities. Power grids require continuous timing to balance loads and keep electricity flowing.
  • Transportation. Aviation, rail, and maritime rely on PNT to keep people and goods moving safely.
  • Governments. Civil organizations depend on trusted time for coordination and resilience. 

When GPS or GNSS signals are lost or compromised, these systems are at risk. Iridium PNT provides assurance that accurate time is available everywhere, right now.

Validated by U.S. Government Standards

The National Institute of Standards and Technology (NIST) has independently validated Iridium PNT as a trusted source of time. Testing confirmed that Iridium PNT delivers precise synchronization even where GPS cannot reach.

This recognition underscores Iridium PNT as a reliable, standards-backed solution. It provides industries and governments with confidence that their most critical systems will remain synchronized and secure under any conditions.

Stronger, Resilient, Always Available

The signal transmitted from the Iridium LEO satellite constellation is 1,000 times stronger than GPS/GNSS, making it effective in places where traditional signals fail, from data centers and telecom hubs to secure government facilities.
