摘要
本文利用LAGEOS-1卫星的激光测距资料,从1990年至1994年,每半年取90天资料,用统计轨道方法,多级复弧法解得10组地球引力常数GM值,取加仅平均值后,最终结果为GM=398600.44181(±0.
The paper gives a weighted mean of GM from a group of 10 values of GM which were determined from 10 groups of LAGEOS-1 Satellite Laser Ranging (SLR)data of 90 days Per half year from 1990 to 1994 with method of statistical orbits determination and with method of multistage multiarc. It isGM=398600.44181(±0.00023) km3/ s2.
