A new way of obtaining precision, UTC traceable time and frequency has come of age, made possible by the rapidly expanding, global deployment of CDMA.  In essence, the CDMA base stations act as repeaters of the GPS timing information they receive from the satellites.  The spread-spectrum modulation scheme employed by the IS-95 CDMA system allows this GPS time reference to be extracted from the base station transmissions with a high degree of precision.  Presented at Precise Time and Time Interval Systems and Applications (PTTI) Meeting in November 2000.
