The aim of the new generation of Global Geodetic Observing System is a millimeter-level
accuracy in positioning, with a crucial role to be played by Global Navigation Satellites …

Future generations of global navigation satellite systems (GNSSs) can benefit from optical
technologies. Especially optical clocks could back-up or replace the currently used …

Satellite navigation is more and more important in a plethora of very different application
fields, ranging from bank transactions to shipping, from autonomous driving to aerial …

The paper presents results of precise orbit and Earth parameter determination based on full-
scale simulations of a potential future GNSS, with the name of Kepler, recently proposed by …

Recently, there has been significant interest in providing positioning, navigation, and timing
(PNT) capability from low-Earth orbit (LEO) satellites. Providing PNT independently of …

We have developed a compact vacuum system for laser cooling and spectroscopy of neutral
thulium atoms. Compactness is achieved by obviating a classical Zeeman slower section …

Investigating and verifying the connections between the foundations of quantum mechanics
and general relativity will require extremely sensitive quantum experiments. To provide …

Abstract Currently, Global Navigation Satellite Systems (GNSS) do not contribute to the
realization of origin and scale of combined global terrestrial reference frame (TRF) solutions …

BOOST (BOOst Symmetry Test) is a proposed space mission to search for Lorentz
invariance violations and aims to improve the Kennedy-Thorndike parameter constraint by …

Global Navigation Satellite Systems receivers use pseudorange measurements for
positioning and time determination. The control system uses the same measurements for …
