The excellent performance of optical clocks offers new prospects for applications as well as fundamental research. Applications include the operation of optical clocks for time keeping and relativistic geodesy.

We are now working on a new apparatus for an optical lattice clock with strontium atoms, which is designed to be transportable. This kind of clocks, that can be operated outside the laboratory, can be used for direct frequency comparison between distant experiments and local measurements of the geo-potential (relativistic geodesy). The portable apparatus allows to resolve the clock transition with few Hertz linewidth. The evaluation of the uncertainty budget is ongoing. In February 2016 a first geodesy experiment is planned.

This work is supported by QUEST, DFG (RTG 1729, CRC 1128), EU-FP7 (SOC2, FACT) and EMRP (ITOC, QESOCAS). The EMRP is jointly funded by the EMRP participating countries within EURAMET and the European Union.
