An international collaboration between the NICT, INRIM, INAF and BIPM has successfully achieved the frequency comparison of distant optical clocks using two independent radio techniques, VLBI and IPPP.
Two-Way Satellite Time and Frequency Transfer, improved by the Software-Defined Radio (SDR) receiver, has been used for Circular T calculation for the first time in March 2020.
Starting from March 2020, the BIPM Time Department is providing additional graphical information concerning the use of Primary and Secondary Frequency Standards (PSFS) in UTC.
