The '''Standard Time and Frequency Signal''' (STFS) is a [[Radiocommunication service]] providing the transmission of specified [[frequency]] and [[time]] signal, of [[Standardization|stated]] high precision, intended for general reception in the United States and beyond. The radio signals are broadcast on very precise [[Carrier signal|carrier]] frequencies by the [[United States Naval Observatory|U.S. Naval Observatory]] and the [[National Institute of Standards and Technology]] (NIST), formerly the National Bureau of Standards (NBS). The technical specification of that particular service is in line to the provisions of the [[International Telecommunication Union|International Telecommunication Union´s]] (ITU) [[ITU Radio Regulations|Radio Regulations]] (RR)<ref>ITU Radio Regulations, Section IV. Radio Stations and Systems – Article 1.53, definition: ''standard frequency and time signal service''</ref>
