GPS Time Transfer

The NIST Time and Frequency Division participates in a number of time transfer experiments and programs that utilize the Global Positioning System (GPS) satellites. Several GPS measurement techniques are used for national and international clock comparisons and related research activities. Most recent data from the NIST primary GPS receiver is here.
