TL;DR: By using ordinary satellites with laser reflectors and providing a second independent detection port and laser pulse timing unit with an independent time scale, it is possible to evaluate many aspects of the proposed time transfer link before the ACES launch.

TL;DR: Atomic Clock Ensemble in Space (ACES) is an ESA mission in fundamental physics based on a new generation of clocks operated in the microgravity environment of the International Space Station.

TL;DR: In this paper, the authors report on results of research and development in the field of solid state single photon detectors at the Czech Technical University in Prague over the last 20 years, including the development of avalanche photodiodes specifically designed for single photon counting devices based on various semiconductor materials.

TL;DR: The evolution of the ILRS network and the emergence of a new generation of SLR station, operating at kHz repetition rates, firing ultra-short laser pulses that are timestamped by epoch timers accurate to a few picoseconds are described.

TL;DR: In this article, an analysis of the influence of the internal delays and their temperature dependence on the TWOTT process considering two different configurations of the terminals with the feedback coupling in optical and electrical domains was performed.
