VLBI

基本解释

Theory of VLBI satellite point positioning is discussed in this paper.
讨论了VLBI单点定位的基本原理,建立了单点定位的数学模型。
The Very-Long-Baseline Interferometry (VLBI) is one of the most powerful techniques for astronomy and geodesy.
甚长基线干涉测量(VLBI)是天文学和测地学研究中的重要观测技术之一。
With advance of metrical precision for space geodesy techniques (such as VLBI, LLR, SLR and GPS), more and more request to the TRS is put forward.
随着空间大地测量技术（VLBI、LLR、SLR和GPS等）的发展，对地球参考系也提出了越来越高的要求。
It was indicated that the real accuracy of velocity field by GPS or VLBI reached 1 mm/a,and SLR 2 mm/a.
SLR实测台站地心速度已经达到2 mm/a的精度。
As shown by images from VLBI, HST, Chandra etc. , the jets are highly relativistic and collimated.
从VLBI、HST和Chandra等观测设备拍到的图像中，我们可以推测喷流是以相对论速度运动的，并可看出它们有很高的准直性。
