Analysis of Lunar Laser and ALSEP VLBI Data for Geodetic Purposes.

Abstract

The M.I.T. Planetary Ephemeris Program has been used to perform simulated least squares estimates of geodetic and other parameters relevant to the analysis of lunar laser ranging observations. These observations can produce improved estimates of (a) observing station locations, (b) variations in the diurnal rotation rate, (c) polar motion, and (d) the earth's gravitational constant. Since the laser data are highly sensitive to the lunar physical libration, differential very-long-baseline interferometry observations of the ALSEP transmitters have been processed to aid in the analysis of the laser data.
