Abstract :
Since 1967 the National Bureau of Standards has improved its Traditional radio broadcast services from radio stations WWV, WWVH, and WWVB and introduced several new services to meet changing needs. The new services are described briefly, including the GOES satellite time code, the Frequency Measurement Service using Loran-C and WWVB, and the Global Time Service based on the GPS satellite common-view technique.
