... Deep Space Network.42 Other time-transfer methods that utilize a single GPS satellite, as well as methods that require observations from multiple satellites, are used for a number of scientific research activities that require precise time synchronization of equipment located in different laboratories.43 40 UTC is often referred to as Greenwich Mean Time because it refers to the time of day in Greenwich, England (U.K.~. 4t The official international timing center in the United States is the National Institute of Standards and Technology (NIST)
