Two members of our consortium gave invited talks during the opening session of CLEO 2019. Project coordinator Helen Margolis from NPL spoke about ‘Optical clocks: from International timekeeping to gravity potential measurement’, immediately followed by Tanja Mehlst√§ubler from LUH on ‘Ultrastable optical atomic clocks for geodesy’. As part of these presentations, both Helen and Tanja spoke about work planned within the scope of the ROCIT project.
