Analytical framework for mutual approximations -- Derivation and application to Jovian satellites
M. Fayolle, D. Dirkx, P. N. A. M. Visser +1
The apparent close encounters of two satellites in the plane of the sky, called mutual approximations, have been suggested as a different type of astrometric observation to refine…
Result of the MICROSCOPE Weak Equivalence Principle test
Pierre Touboul, Gilles Métris, Manuel Rodrigues +44
The space mission MICROSCOPE dedicated to the test of the Equivalence Principle (EP) operated from April 25, 2016 until the deactivation of the satellite on October 16, 2018. In th…
The science case and challenges of space-borne sub-millimeter interferometry
Leonid I. Gurvits, Zsolt Paragi, Ricardo I. Amils +51
Ultra-high angular resolution in astronomy has always been an important vehicle for making fundamental discoveries. Recent results in direct imaging of the vicinity of the supermas…
Space test of the Equivalence Principle: first results of the MICROSCOPE mission
Pierre Touboul, Gilles Métris, Manuel Rodrigues +31
The Weak Equivalence Principle (WEP), stating that two bodies of different compositions and/or mass fall at the same rate in a gravitational field (universality of free fall), is a…
Laser and Radio Tracking for Planetary Science Missions - A Comparison
Dominic Dirkx, Ivan Prochazka, Sven Bauer +4
At present, tracking data for planetary missions largely consists of radio observables: range-rate range and angular position. Future planetary missions may use Interplanetary Lase…
The MICROSCOPE mission: first results of a space test of the Equivalence Principle
Pierre Touboul, Gilles Métris, Manuel Rodrigues +40
According to the Weak Equivalence Principle, all bodies should fall at the same rate in a gravitational field. The MICROSCOPE satellite, launched in April 2016, aims to test its va…
On the contribution of PRIDE-JUICE to Jovian system ephemerides
Dominic Dirkx, Leonid I. Gurvits, Valery Lainey +5
The JUICE mission will perform detailed measurements of the properties of the Galilean moons, with a nominal in-system science-mission duration of about 3.5 years. Using both the r…
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…
Space-time Dynamics Estimation from Space Mission Tracking Data
Dominic Dirkx, Ron Noomen, Pieter Visser +2
Many physical parameters that can be estimated from space mission tracking data influence both the translational dynamics and proper time rates of observers. These different proper…
