Interpretation of geodesy experiments in non-Newtonian theories of gravity [PDF]
Classical and quantum gravity, 2018 The tests of the deviations from Newton's or Einstein's gravity in the Earth neighbourhood are tied to our knowledge of the shape and mass distribution of our planet. On the one hand estimators of these "modified" theories of gravity may be explicitly Earth-model-dependent whilst on the other hand the Earth gravitational field would act as a systematic

Gravitational-Wave Geodesy: A New Tool for Validating Detection of the Stochastic Gravitational-Wave Background [PDF]
, 2018 A valuable target for advanced gravitational-wave detectors is the stochastic gravitational-wave background. The stochastic background imparts a weak correlated signal into networks of gravitational-wave detectors, and so standard searches for the gravitational-wave background rely on measuring cross-correlations between pairs of widely-separated ...

Chronometric geodesy: methods and applications [PDF]
Fundamental Theories of Physics, 2018 In section 2, we introduce fundamental concepts of GR concerning the measurement of time, relativistic reference systems and we review the recent literature of chronometric geodesy. In section 3 we introduce the theory of frequency standard comparisons, beginning with the Einstein equivalence principle, followed by the description of the frequency ...

Journal of Physics: Conference Series, 2016 Quantum metrology enables new applications in geodesy, including relativistic geodesy. The recent progress in optical atomic clocks and in long-distance frequency transfer by optical fiber together pave the way for using measurements of the gravitational frequency redshift for geodesy. The remote comparison of frequencies generated by calibrated clocks

Advanced relativistic VLBI model for geodesy
Journal of Geodesy, 2017 Our present relativistic part of the geodetic VLBI model for Earthbound antennas is a consensus model which is considered as a standard for processing high-precision VLBI observations. It was created as a compromise between a variety of relativistic VLBI

Recent Advances in Marine Geodesy of China [PDF]
Journal of Geodesy and Geoinformation Science, 2023 The ocean accounts for approximately 71% of the total area of the Earth. Whether it is studying the shape of the Earth itself through geodesy or the future development of earth system science, strengthening the construction of ocean geodesy disciplines ...

A simplified gravitational reference sensor for satellite geodesy [PDF]
Journal of Geodesy, 2021 A simplified gravitational reference sensor (S-GRS) is an ultra-precise inertial sensor for future Earth geodesy missions. These sensors measure or compensate for all non-gravitational accelerations of the host spacecraft to remove them in the data ...
