Here we wish to discuss the improvements obtainable in the measurement of the general relativistic Lense—Thirring effect with the LAGEOS and LAGEOS II satellites, in terms of reliability of the evaluation of the systematic error and reduction of its magnitude, due to the new CHAMP and GRACE Earth gravity models.

On the reliability of the so-far performed tests for measuring the Lense-Thirring effect with the LAGEOS satellites

The improvement of the Earth gravity field estimation and its benefits in the atmosphere and fundamental physics
Abstract In the present decade, Earth’s explorer missions such as CHAMP, GRACE and GOCE are going to dramatically improve the knowledge of the Earth’s gravity field. The deep knowledge of the gravity…
On the possibility of testing the Dvali–Gabadadze–Porrati brane-world scenario with orbital motions in the Solar System
Recently it has been suggested to use the perigee of the proposed LARES/WEBER-SAT satellite in order to measure the secular precession which would be induced on such a Keplerian orbital element by a…
On a possible new approach for investigating the secular variations of the low-degree geopotential coefficients
In this paper we try to suggest a possible novel method to determine some selected even zonal harmonics J_l of the Earth's geopotential. Time series many years long of suitably linearly combined…
On the effects of Dvali–Gabadadze–Porrati braneworld gravity on the orbital motion of a test particle
In this paper, we explicitly work out the secular perturbations induced on all the Keplerian orbital elements of a test body to order in the eccentricity e by the weak-field long-range modifications…

The Impact of the Static Part of the Earth's Gravity Field on Some Tests of General Relativity with Satellite Laser Ranging
In this paper we calculate explicitly the classical secular precessions of the node Ω and the perigee ω of an Earth artificial satellite induced by the even zonal harmonics of the static part of the…

SummaryWe describe a new method to obtain the first direct measurement of the Lense-Thirring effect, or dragging of inertial frames, and the first direct detection of the gravitomagnetic field. This…

Reassessment of the error modelling of non-gravitational perturbations on LAGEOS II and their impact in the Lense–Thirring determination. Part I
Abstract The perturbative effects due to both direct solar radiation pressure and Earth albedo radiation pressure have been investigated on LAGEOS II. In particular, the effects on the eccentricity…
The 1995-99 measurements of the Lense-Thirring effect using laser-ranged satellites
In general relativity a current of mass-energy, such as a spinning body, gives rise to peculiar phenomena on bodies, particles and clocks in its vicinity, which are not predicted by the Newtonian…
Measuring the relativistic perigee advance with satellite laser ranging
The pericentric advance of a test body by a central mass is one of the classical tests of general relativity. Today, this effect is measured with radar ranging by the perihelion shift of Mercury and…
