Abstract
The use of ultra-precise optical clocks in space will allow for a range of new applications in the fields of fundamental physics (tests of Einstein's theory of General Relativity, time and frequency metrology by means of the comparison of distant terrestrial clocks), geophysics (mapping of the gravitational potential of Earth), and astronomy (providing local oscillators for radio ranging and interferometry in space). Within the ELIPS program of ESA, the 'Space Optical Clocks' (SOC) project aims to install and to operate an optical lattice clock on the ISS towards the end of this decade. In this project two accurate transportable lattice optical clock demonstrators having relative frequency instability below 1×10-15 at 1 s integration time and relative inaccuracy below 5×10-17 are under development. Crucial requirements are moderate volume, electrical power consumption and mass, and robustness. Furthermore, a modular concept is favourable.
