Time division duplex (TDD) telecom systems cannot operate without phase and time alignment, and today the reference is a GPS receiver at the tower. LightTime delivers traceable time into the aggregation site with proof, so the network holds alignment when GPS can't.
Synchrophasors, line-differential protection, and event recording all assume every substation clock agrees. GPS meets the accuracy bar; what it cannot do is prove the clocks were right, or break a tie when they disagree. LightTime adds the independent reference and the forensic-grade record.
Regulators require clocks synchronized to the national standard and timestamps that can be reconstructed. LightTime delivers traceable time into the colocation site with a signed record for every interval, so compliance is easy and resilient.
Distributed databases, consensus protocols, and transaction ordering all run better the tighter the clocks agree, and every tenant in the building is solving the same problem separately with their own GPS antenna. One TimeHub in the meet-me room serves them all.
Ground stations, launch ranges, and mission operations centers keep time by GPS like everyone else. A TimeHub brings traceable, GNSS-independent time to ground facilities today, and the orbital service in development will carry the same time and proof to the space assets themselves.
Military installations, command and control centers, test ranges, and radar and sensor sites all depend on clocks that agree, and most of them get their time from GPS. In a contested environment that signal is the first thing to go, and a spoofed clock is an attack, not just an outage. LightTime gives these facilities a time source that does not depend on GNSS at all, traceable to national timing laboratories, with a signed record of every interval.
Water systems, transportation, rail, broadcasting, and public safety dispatch all inherit GPS time through equipment that never checks it. LightTime brings the same independent reference and proof to any facility.
