60年距离测量的演变

新中国成立60年来,距离测量方法所发生的巨大变化是,20世纪50年代末期,光速测距仪和微波测距仪的推广应用,开创了量距不用尺的新时代;20世纪60年代中期,测地型激光测距仪的快速发展,将光波测距推向了高精度远测程的新境界;几乎与此同时,卫星激光测距和甚长基线射电干涉测量技术的测地实用化,使得测地工作者能够测量远达数千千米的站间距离;20世纪80年代初期,GPS卫星测量技术的问世,使得测地工作者步入了快速高效量距不见站的新天地。距离测量的这种演变,也是测绘科学技术进步的一大缩影。

The Distance Measurement Evolution in 60 Years

Since the 60th anniversary of the People Republic Of China,the distance measurement method has changed dramatically,mainly in the following areas: in the late 1950s,the popularization of Geodimeter and Tellurometer has created a new era,being the distance surveying without rulers;in the mid 1960s,the light wave rangers step into the new realm of a far distance and high accuracy because the rapid development of Laser rangers;almost at the same time,Satellite Laser Ranging and Very Long Baseline Radio Interfe...
