摘要: A summary of the results obtained for a new comprehensive geodetic parameter solution from analysis LAGEOS laser ranging data period May 1976 to end 1982 is presented. Estimates each component polar motion and earth rotation, station coordinates, value earth's gravitational constant GM, elements orbit comprise this SL5.1AP solution. The differ previously published values primarily through incorporation more rigorous dynamic models ocean solid tides. precision parameters are on average 5-marc sec motion, 0.2-ms length day, better than 5-cm center-of-mass positioning, 3-cm global baselines, 2-cm regional baselines. An assessment contribution systematic errors in interstation distance determination
