Test of gravitomagnetism with satellites around the Earth

Abstract

We focus on the possibility of measuring the gravitomagnetic effects due to the rotation of the Earth, by means of a space-based experiment that exploits satellites in geostationary orbits. Due to the rotation of the Earth, there is an asymmetry in the propagation of electromagnetic signals in opposite directions along a closed path around the Earth. We work out the delays between the two counter-propagating beams for a simple configuration, and suggest that accurate time measurements could allow, in principle, to detect the gravitomagnetic effect of the Earth. * Electronic address: matteo.ruggiero@polito.it † Electronic address: angelo.tartaglia@polito.it

Gravitoelectromagnetism, Solar System Tests, and Weak-Field Solutions in f (T,B) Gravity with Observational Constraints

“…The MGS spacecraft [54,55] tested gravitomagnetism effects about Mars, while there have also been tests about the Sun [56]. For this reason, there have been a number of ambitious proposals put forward in recent years to further test this relativistic effect and to increase the experimental precision of the observations [57][58][59][60].…”

Quagnetic Field Part (I)

“…(s) With experimental way, it is suggested that the gravitomagnetic effect of the earth can be measured by exploiting the propagation times considering special as well as general theory of relativity time corrections of counter propagating two electromagnetic signals emitted, transmitted and received by geostationary three satellites around the earth. Here commoving electromagnetic pulse with satellite movement takes more time to circle the same and vice-a-versa [14].…”

The effect of stationary axisymmetric spacetimes in interferometric visibility

“…However, when a gravitational field is present the situation is essentially the same, except for corrections produced by curvature and angular momentum of the rotating body [6]. Until now, several approaches has been taken to derive and to propose experiments to verify the gravitomagnetic clock effect [7][8][9][10][11][12][13][14].…”
