摘要: Coordinated Universal Time (UTC) is available worldwide via the Global Positioning System (GPS). The UTC disseminated by GPS referenced to US Naval Observatory Master Clock UTC(USNO) which regularly steered and maintained as close possible Bureau International des Poids et Mesures (BIPM), international time scale. This paper will describe role of USNO in monitoring steps involved ensure its accuracy user. also discuss other sources process UTC(BIPM).
