Iridium Satellite Time and Location
The first truly global low-Earth orbit (LEO) positioning, navigation, and timing (PNT) solution provides resilience with exceptional reliability, high security, and signal strength greater than GPS.
1000x Stronger Than GPS
An alternative PNT service, Iridium STL® complements GPS/GNSS. Using the Iridium® satellite constellation, STL is unique among PNT offerings: Its signals are powerful, extremely secure, and available worldwide.
Iridium STL penetrates indoors and signal-challenged urban canyons where high-rise buildings create multipath issues for GPS.
Iridium PNT ASIC
Planned for commercial availability in mid-2026, the Iridium PNT ASIC will enable resilient, secure primary or backup PNT capabilities in an ultra-compact chip. Learn more about Iridium PNT ASIC.
Government PNT Initiatives for Critical Infrastructure Resilience
Governments around the world are taking decisive steps to strengthen national resilience through the responsible use of PNT. Learn more about government initiatives for critical infrastructure resilience.
