Advanced relativistic VLBI model for geodesy
Michael Soffel, Sergei Kopeikin, Wen-Biao Han
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 observati…
Normal gravity field in relativistic geodesy
Sergei M. Kopeikin, Igor Yu. Vlasov, Wen-Biao Han
Modern geodesy is subject to a dramatic change from the Newtonian paradigm to Einstein's theory of general relativity. This is motivated by the ongoing advance in development of qu…
Theia: Faint objects in motion or the new astrometry frontier
The Theia Collaboration, Celine Boehm, Alberto Krone-Martins +96
In the context of the ESA M5 (medium mission) call we proposed a new satellite mission, Theia, based on relative astrometry and extreme precision to study the motion of very faint…
High Performance Clocks and Gravity Field Determination
J. Müller, D. Dirkx, S. M. Kopeikin +4
Time measured by an ideal clock crucially depends on the gravitational potential and velocity of the clock according to general relativity. Technological advances in manufacturing…
