In this session we search for contributions of general interest within the geodesy community. Although the range is entirely open we focus this year on relativistic geodesy. Advances of optical atomic clocks with stability at the 10-18 level and availability of accurate spaceborne gravimetry/gradiometry sensors provide prospective potential for geopotential determination employing relativistic geodetic approaches and development of gravity field model at unprecedented resolution and accuracy. The purpose of this session is to solicit papers including but not limited to: (1) determination of gravitational potential on ground and in space based on relativistic geodetic approaches, including clock transportation comparison (CTC), gravity frequency shift (GFS), satellite frequency signal transmission (SFST), optic-fiber frequency transfer (OFFT); (2) recent developments and various experiments related to atomic clocks and time-frequency science; (3) novel mathematical techniques leading to ultra-high degree global and regional gravity field/geoid determination, including optimal basis function representations and the corresponding modeling; gravity field modeling based on relativistic geodetic approaches; and (4) local and global geoids towards improving unification of world height system, and unification of world height system based on relativistic geodetic approaches.
