The research activities carried out within the ITOC project were structured into five technical workpackages and an associated researcher excellence grant (REG):

WP1: Local frequency comparisons and absolute frequency measurements

WP2: Frequency comparisons using transportable optical clocks

WP3: Relativistic timescales and geodesy

WP4: Proof-of-principle relativistic geodesy experiment

WP5: Remote clock comparisons via satellite links and analysis for timescale steering

REG: Gravity potential for optical clock comparisons

The research within this EURAMET joint research project receives funding from the European Community's Seventh Framework Programme, ERA-NET Plus, under Grant Agreement No. 217257.
