In most of the recent determinations of the geocentric gravitational coefficient (GM) of the Earth, the laser ranging data to the Lageos satellite have had the greatest influence on the solution. These data, however, have generally been processed with a small but significant error in one of the range corrections. In a new determination of GM using the corrected center-of-mass offset, a value of 398600.4415 km3/sec2 (including the mass of the atmosphere) has been obtained, with an estimated… 

Earth scale defined by modern satellite ranging observations

Recent advances in Satellite Laser Ranging (SLR) allow us to determine an improved value of the geocentric gravitational coefficient (GM) of 398600.4419 +/− .0002 km³/sec² (one sigma). This value is

Absolute Earth Scale from SLR Measurements

Since the LAGEOS-I satellite was launched in 1976, the systematic instrument error of the best satellite laser ranging observatories has been steadily reduced. Advances in overall system accuracy, in

STEADY CHANGE IN FLATTENING OF THE EARTH: THE PRECESSION CONSTANT AND ITS LONG-TERM VARIATION

Variation in the second-degree zonal harmonic J2 of the Earth's gravitational potential is discussed and its impact on the coefficient H associated with the precession constant determined. The

Geopotential from space techniques

The monitoring of the perturbed motion of artificial satellites since the 1960's has provided a valuable resource for improved activities in geodesy. These observations and the improved geodetic

Earth scale below a part per billion from Satellite Laser Ranging

Since the LAGEOS I satellite was launched in 1976, the systematic instrument error of the best satellite laser ranging observatories has been steadily reduced to the current level of only a few

Constraint on Intermediate-Range Gravity from Earth-Satellite and Lunar Orbiter Measurements, and Lunar Laser Ranging

In the experimental tests of gravity, there have been considerable interests in the possibility of intermediate-range gravity. In this paper, we use the earth-satellite measurement of earth gravity,

Placing direct limits on the mass of earth-bound dark matter

We point out that by comparing the total mass (in gravitational units) of the earth–moon system, as determined by lunar laser ranging, with the sum of the lunar mass as independently determined by

Estimation of the accuracy of geopotential models

SummaryThe new Geopotential Model Testing (GMT) method has been theoretically developed and practically applied. It is free of any hypothesis, the limiting factors are the accuracy of the geocentric

High Resolution Regional Geoid Computation

A new methodology for the high-resolution geoid computation without application of the Stokes integral has been developed. This methodology renders simultaneously the observables of the type gravity

Determination of the gravitational coefficient of the Earth from near‐Earth satellites

Laser range, doppler and altimeter data collected from 14 near-Earth satellites have been combined to determine the value of the geocentric gravitational coefficient (GM) of the Earth. A long-arc

Determination of the geocentric gravitational constant from laser ranging on near-Earth satellites

Laser range observations taken on the near-earth satellites of Lageos (a = 1.92 e.r.), Starlette (a = 1.15 e.r.), BE-C (a = 1.18 e.r.) and Geos-3 (a = 1.13 e.r.), have been combined to determine an

The LAGEOS spacecraft is unique in that both its design and orbital characteristics were specifically chosen for high-resolution geodynamic studies using satellite laser ranging techniques. Since its

The Earth-induced Yarkovsky thermal drag is known to be the principal drag mechanism for LAGEOS. In combination with charged and neutral particle drag this thermal drag can account for all of the

Yarkovsky Thermal Drag on LAGEOS

Thermal drag accounts for about 70% of the observed average drag on LAGEOS. This estimate is based on a new thermal model which includes the radiative heat transfer between the retroreflector, its
