A new laser-ranged satellite for General Relativity and space geodesy: I. An introduction to the LARES2 space experiment [PDF]
We introduce the LARES 2 space experiment recently approved by the Italian Space Agency (ASI). The LARES 2 satellite is planned for launch in 2019 with the new VEGA C launch vehicle of ASI, ESA and ELV. The orbital analysis of LARES 2 experiment will be carried out by our international science team of experts in General Relativity, theoretical physics,

Optomechanical Accelerometers for Geodesy [PDF]
We present a novel optomechanical inertial sensor for low-frequency applications and corresponding acceleration measurements. This sensor has a resonant frequency of 4.715 (1) Hz, a mechanical quality factor of 4.76(3) × 105, a test mass of 2.6 g, and a projected noise floor of approximately 5 × 10−11 ms−2/Hz at 1 Hz.

Operational significance of the deviation equation in relativistic geodesy [PDF]
Deviation equation: Second order differential equation for the 4-vector which measures the distance between reference points on neighboring world lines in spacetime manifolds. Relativistic geodesy: Science representing the Earth (or any planet), including the measurement of its gravitational field, in a four-dimensional curved spacetime using ...

REVEL: A model for Recent plate velocities from space geodesy
[1] We present a new global model for Recent plate velocities, REVEL, describing the relative velocities of 19 plates and continental blocks. The model is derived from publicly available space geodetic (primarily GPS) data for the period 1993–2000.

Atomic clocks: new prospects in metrology and geodesy [PDF]
We present the latest developments in the field of atomic clocks and their applications in metrology and fundamental physics. In the light of recent advents in the accuracy of optical clocks, we present an introduction to the relativistic modelization of frequency transfer and a detailed review of chronometric geodesy.

Space geodesy constrains ice age terminal deglaciation: The global ICE‐6G_C (VM5a) model
A new model of the last deglaciation event of the Late Quaternary ice age is here described and denoted as ICE‐6G_C (VM5a). It differs from previously published models in this sequence in that it has been explicitly refined by applying all of the ...
