Proceedings of the 52nd Annual Precise Time and Time Interval Systems and Applications Meeting.
TWSTFT has been one of the most popular techniques used for comparison of remote atomic clocks. It typically employs the code-phase of a signal modulated by a pseudorandom noise (PN) code sent and received by microwave link via a geostationary teleco

Metrologia, IOP Publishing, 2019, 56 (3), pp.035004. ⟨10.1088/1681-7575/ab14bb⟩
The measurement of the time difference between two heterogeneous electrical sources is a necessary task in several branches of metrology. In particular the dissemination of Coordinated Universal Time (UTC) around the world requires one to quantify th
