The Variation in J2 and in the Moments of Inertia: Satellite Results and Consequences for the Angular Momentum Budget of the Earth-Moon-Sun System

  • M. Burša

Abstract

The latest results of determination of the secular variation in the Moon’s mean mo­tion n purely of tidal origin on the basis of Lunar Laser Ranging (LLR) and Satellite Laser Ranging (SLR) techniques, as well as of the nontidal variation in the second zonal geopotential harmonic J2 on the basis of LAGEOS orbit dynamics, make it possible to refine the residuum in the Earth-Moon-Sun angular momentum budget. The tidal and nontidal secular variation in the angular velocity ω of the Earth’s rota­tion can be also refined.
