000004219 520__ $$aA GNSS timing receiver can generate a time pulse aligned to GNSS System Time (GNSST) or to the predicted UTC transmitted by GNSS. In the case of GPS, GNSST is GPS Time, and the predicted UTC is UTC(USNO). USNO is the United States Naval Observatory. In the case of Galileo, GNSST is Galileo System Time (GST), and the predicted UTC is the average of five European UTC(k) laboratories. Using GNSST or its associated UTC realization is enough for many synchronization and time stamping applications, but in some cases (for example in the financial sector) it is necessary to trace the timing solution to the legal time scale of the user’s country, which is normally a UTC(k) laboratory as for example UTC(NIST) in the USA, UTC(PTB) in Germany, or UTC(ROA) in Spain. Traceability to a UTC(k) time scale can be achieved a-posteriori by means of Common-View (CV) time transfer between the receiver and the UTC(k) laboratory. This paper provides practical recommendations for CV traceability computations, focused on affordable, single-frequency timing receivers.
