Additional Description

Abstract

Recent advances in Satellite Laser Ranging (SLR) allow us to determine an improved value of the geocentric gravitational coefficient (GM) of 398600.4419+or-.0002 km (cubed)/sec (sq)(one sigma). This value is based on recent SLR observations of teh LAGEOS I satellite; general relativity predicts mu = 1.
