Inserting FS725 Rubidium Clock as a Fail-Safe Mechanism in the aLIGO Timing System Chain

Document #:

LIGO-T1500387-v1

Document type:

T - Technical notes

Abstract:

This document demonstrates that by inserting a properly constructed Rubidium clock between the GPS Receiver and the Timing Master allows the timing system to tolerate the loss of GPS system for many hours without compromising aLIGO’s timing specifications.
