Abstract : The National Institute of Standards and Technology (NIST) operates a 6O-kMz timing signal transmitten known as WWVB, at a site near Fort Collins, Colorado. This system has redundant transmitters and antenna systems and was thought to radiate about 13 kW. NIST commissioned the Naval Command Control and Ocean Surveillance Center Research, Development, Test and Evaluation Division (NRaD) to make baseline performance measurements that could support the design of a 6-dIB upgrade. This document presents these measurements. A second document, NRaD TR 1692, provides a summary of the measurement results, a recommended upgrade configuration, and recommendations.
