The determination of crustal motions using laser ranging to Lageos-2 and Lageos-1

摘要

During the period October 1992 through June 1993, Center for Space Research efforts continued on four areas: (1) production of a solution for terrestrial reference frame including site positions, velocities, and Earth orientation and rotation spanning the entire Lageos-1 mission, (2) production of a solution for terrestrial reference frame including site positions and Earth orientation spanning the Lageos-2 mission, independently from Lageos-1, (3) evaluation of numerical characteristics of the integration of the Lageos-2 orbit, (4) evaluation of contributions of Lageos-1 and Lageos-2 to temporal variations in the geopotential and 18.6 year tidal response of the Earth, and (5) attendence and participation in Lageos-2 Investigator Working Group Meetings and Committees.
