Solid and Ocean Earth Tides and the Detection of Some Gravitomagnetic Effects
نویسنده
چکیده
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.

Tidal satellite perturbations and the Lense-Thirring effect
The tiny general relativistic Lense-Thirring effect can be measured by means of a suitable combination of the orbital residuals of the nodes of LAGEOS and LAGEOS II and the perigee of LAGEOS II. This observable is affected, among other factors, by the Earth’ s solid and ocean tides. They induce long-period orbital perturbations that, over observational periods of few years, may alias the detect...
متن کاملSatellite gravitational orbital perturbations and the gravitomagnetic clock effect
In order to detect the gravitomagnetic clock effect by means of two counter-orbiting satellites placed on identical equatorial and circular orbits around the Earth with radius 7000 km their radial and azimuthal positions must be known with an accuracy of δr = 10−1 mm and δφ = 10−2 mas per revolution. In this work we investigate if the radial and azimuthal perturbations induced by the dynamical ...
متن کاملEarth tides and Lense-Thirring effect
The general relativistic Lense-Thirring effect can be measured by inspecting a suitable combination of the orbital residuals of the nodes of LAGEOS and LAGEOS II and the perigee of LAGEOS II. The solid and ocean Earth tides affect the recovery of the parameter by means of which the gravitomagnetic force is accounted for in the combined residuals. Thus an extensive analysis of the perturbations ...
متن کاملEffects of Earth tesseral and sectorial tides on the determination of the Lense-Thirring effect
The general relativistic Lense-Thirring effect can be detected by means of a suitable combination of orbital residuals of the laser-ranged LAGEOS and LAGEOS II satellites. While this observable is not affected by the orbital perturbation induced by the zonal Earth solid and ocean tides, it is sensible to those generated by the tesseral and sectorial tides. The assessment of their influence on t...
متن کاملEffects of Earth tides on LAGEOS and LAGEOS II satellites and their influence on the detection of the Lense-Thirring effect
An extensive analysis of the perturbations induced on node and perigee of LAGEOS and LAGEOS II by solid and ocean Earth tides is carried out in order to assess their influence in the detection of the secular general relativistic Lense-Thirring effect by means of these two satellites. The investigation involves only the terms of degree l = 2 for the solid tides and also the terms of degree l = 3...
