Abstract:	At BEV, in cooperation with PTB and Joanneum Research/TU Graz and the support of BIPM, we have done a calibration of the BEV reference GPS time receiver by using Two-way Satellite Time and Frequency Transfer (TWSTFT). Due to antenna changes, a new calibration of the BEV receiver was necessary. This receiver is the first GPS receiver with calibration through TWSTFT and used for UTC computation. This new calibration technique improves the value of the UTC-UTC (BEV) uncertainty in the Circular T from 5.3 ns down to 3.6 ns.
