Abstract

Optical atomic clocks, due to their unprecedented stability 1-3 and uncertainty 3-6 , are already being used to test physical theories 7,8 and herald a revision of the International System of Units 9,10 . However, to unlock their potential for cross-disciplinary applications such as relativistic geodesy 11 , a major challenge remains: their transformation from highly specialized instruments restricted to national metrology laboratories into flexible devices deployable in different locations 12-14 . Here, we report the first field measurement campaign with a transportable 87 Sr optical lattice clock 12 . We use it to determine the gravity potential difference between the middle of a mountain and a location 90 km away, exploiting both local and remote clock comparisons to eliminate potential clock errors. A local comparison with a 171 Yb lattice clock 15 also serves as an important check on the international consistency of independently developed optical clocks. This campaign demonstrates the exciting prospects for transportable optical clocks.
