Replacing GNSS As The Sole Timing Source
Satellite timing can fail in a second, causing national networks to stop. A new terrestrial timing method removes this single point of failure.
Critical infrastructure operators in telecom, utilities, transportation, defense, and government are being advised to stop depending on GNSS as the only timing source. A single point of failure in satellite timing, whether due to outage, jamming, spoofing, or policy limits, can break synchronization across national networks and disrupt 5G transport, power grid protection, secure links, and safety systems.
These operators need a terrestrial timing source that can maintain network accuracy when GNSS is unavailable, without requiring service changes and without waiting for space-based timing to return.
Microchip’s TimeProvider 4500 v3 grandmaster meets that need by delivering sub-nanosecond time over 800 km of fiber, allowing deployment of grandmaster sites that do not depend on GNSS, closing the gap in complementary PNT.
Author's summary: New terrestrial timing method replaces GNSS.
