The challenge to reliably measure the general relativistic Lense-Thirring effect with a few percent accuracy
نویسنده
چکیده
In this paper we critically analyze the so far performed and proposed tests for measuring the general relativistic Lense-Thirring effect in the gravitational field of the Earth with some of the existing accurately tracked artificial satellites. The impact of the 2nd generation GRACE-only EIGEN-GRACE02S Earth gravity model and of the 1st CHAMP+GRACE+terrestrial gravity combined EIGEN-CG01C Earth gravity model is discussed. The role of the proposed LARES is discussed as well.

متن کاملTowards a few-percent measurement of the Lense-Thirring effect with the LAGEOS and LAGEOS II satellites?
Up to now attempts to measure the general relativistic LenseThirring effect in the gravitational field of Earth have been performed by analyzing a suitable J2 − J4−free combination of the nodes Ω of LAGEOS and LAGEOS II and the perigee ω of LAGEOS II with the Satellite Laser Ranging technique. The claimed total accuracy is of the order of 20-30%, but, according to some scientists, it could be a...
متن کاملOn Possible A-Priori "Imprinting" of General Relativity Itself on the Performed Lense-Thirring Tests with LAGEOS Satellites
The impact of possible a-priori “imprinting” effects of general relativity itself on recent attempts to measure the general relativistic Lense-Thirring effect with the LAGEOS satellites orbiting the Earth and the terrestrial geopotential models from the dedicated mission GRACE is investigated. It is analytically shown that general relativity, not explicitly solved for in the GRACE-based models,...
