Accurate. Secure. Available Now.

Iridium® PNT keeps the world in sync. Our signal works where others fail—indoors, across oceans, in the air, and during GPS and GNSS disruptions. Backed by Iridium’s crosslinked low–Earth orbit satellite constellation, we deliver trusted time and location data for the critical infrastructure we all depend upon.
