LAGEOS激光测距获得的基线长度

THE BASELINES OBTAINED FROM LASER RANGING TO SATELLITE LAGEOS

本文利用1983年9月—1984年10月国际地球自转主联测期间LAGEOS激光测距资料,解算了11个台站间的55条基线,基线的内部精度为±1.5cm;与其它作者和甚长基线干涉测量的几个欧洲和美洲台站间的基线的比较表明,一般的差异不到10cm,特别是本文结果与VLBI的值最大差为4cm,因此,估计外部精度为10cm左右。

The 55 baselines among 11 stations have been estimated from 14-month span of laser ranging to satellite LAGEOS of the MERIT main campaign.The formal standard error is about 1.5cm.The comparison of some baselines obtained by others shows that the agreement of various estimates is fairly good,and the largest difference of our results from the VLBI values is 4cm.Therefore the real accuracy of our baselines is about 10cm.
