The impact of the static part of the Earth’s gravity field on some tests of General Relativity with laser–ranging

چکیده

In this paper we calculate explicitly the secular classical precessions of the node Ω and the perigee ω of an Earth artificial satellite induced by the static, even zonal harmonics of the geopotential up to degree l = 20. Subsequently, their systematic errors induced by the mismodelling in the even zonal geopotential coefficients Jl are compared to the general relativistic secular gravitomagnetic and gravitoelectric precessions of the node and the perigee of the existing laser–ranged geodetic satellites and of the proposed LARES. The impact of the future terrestrial gravity models from CHAMP and GRACE missions is discussed as well. 1

A ug 2 00 9 On possible a - priori “ imprinting ” of General Relativity itself on some tests aimed to test it

We investigate the effect of possible a-priori “imprinting” effects of general relativity itself on satellite/spaceraft-based tests of it. We deal with some performed or proposed time-delay ranging experiments in the Sun’s gravitational field, and with the attempts to measure the Lense-Thirring effect with the LAGEOS satellites orbiting the Earth. It turns out that the “imprint” of general rela...

2D inversion of gravity data in bedrock identification (case study: a part of Qotrum plain in Yazd province)

Introduction The gravity method measures the vertical component of the acceleration at the Earth’s surface. The earth’s gravity field is affected by the density of different rocks and structures. Therefore, this method can be used in mineral exploration or studying the subsurface cavities and structures such as bedrocks, channels, and dikes. Inverse modeling is useful in understanding the p...

Laser Astrometric Test of Relativity: Science, Technology, and Mission Design

The Laser Astrometric Test of Relativity (LATOR) experiment is designed to explore general theory of relativity in the close proximity to the Sun – the most intense gravitational environment in the solar system. Using independent time-series of highly accurate measurements of the Shapiro time-delay (interplanetary laser ranging accurate to 3 mm at ∼2AU) and interferometric astrometry (accurate ...

Spherically Symmetric Solutions in a New Braneworld Massive Gravity Theory

In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the five-dimensional bulk graviton is considered to be massive. The five dimensional nonlinear ghost-free massive gravity theory affects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical s...
