Resilient Precision Time Pilot

The Department of Homeland Security (DHS) is conducting market research to determine technical capabilities for transferring precise time over long-haul fiber that is reproducible, scalable, and sustainable for use by end-users. The goal is to develop a pilot that is resilient to Positioning, Navigation, and Timing (PNT) threats and independent of the Global Positioning System (GPS). The pilot should include a master timing node network, "last mile" timing distribution to end-users, and be traceable to the National Standards Institute and Technology. Some key requirements for the pilot include: • Master Timing Node Network with accuracy of 100 nanoseconds or better and holdover capabilities of 30 days for primary nodes and 1-5 days for secondary nodes • "Last mile" timing distribution to end-users with accuracy of 1 microsecond or better • Timing at both levels must be traceable to UTC(NIST) • The pilot should be scalable, sustainable, and reproducible for use by critical infrastructure end-users • The contractor should work with stakeholder partners and develop documentation to enable other states to reproduce a similar capability
