Solid and ocean tides and the detection of some gravitomagnetic effects
Lorenzo Iorio
TL;DR
This paper discusses how Earth's solid and ocean tides impact the detection of tiny gravitomagnetic effects, such as the Lense-Thirring effect, using artificial satellites and proposed experiments.
Contribution
It analyzes the influence of Earth's tides on measuring gravitomagnetic effects and evaluates their impact on satellite-based experiments.
Findings
Earth tides significantly perturb satellite orbits
Tidal effects must be carefully modeled for accurate measurements
Implications for current and future gravitomagnetic experiments
Abstract
The detection of some tiny gravitomagnetic effects in the field of the Earth by means of artificial satellites is a very demanding task because of the various other perturbing forces of gravitational and non-gravitational origin acting upon them. Among the gravitational perturbations a relevant role is played by the Earth solid and ocean tides. In this communication I outline their effects on the detection of the Lense-Thirring drag of the orbits of LAGEOS and LAGEOS II, currently analyzed, and the proposed GP-C experiment devoted to the measurement of the clock effect.
