An Evaluation of the Beidou Time System (BDT)
Journal of Navigation, 2011The evaluation of Beidou system time is one of the important tasks in constructing and developing the Beidou satellite navigation system. The evaluation methods based on two-way satellite time and frequency transfer method (TWSTFT) and GPS common-view method are proposed in this paper.

Tests of Galileo and BeiDou links for UTC
2019 Joint Conference of the IEEE International Frequency Control Symposium and European Frequency and Time Forum (EFTF/IFC), 2019Time links used in UTC computation are based on Global Navigation Satellite Systems and on the Two Way Satellite Time and Frequency Transfer technique. For GNSS, GPS forms the basis of all links and GLONASS has been also used. The other global systems Galileo and BeiDou have reached operational status and we study in this paper how they could ...
