VLBI

基本解释

Theory of VLBI satellite point positioning is discussed in this paper.
討論了VLBI單點定位的基本原理,建立了單點定位的數學模型。
The Very-Long-Baseline Interferometry (VLBI) is one of the most powerful techniques for astronomy and geodesy.
甚長基線乾涉測量(VLBI)是天文學和測地學研究中的重要觀測技術之一。
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.
隨著空間大地測量技術（VLBI、LLR、SLR和GPS等）的發展，對地球蓡考系也提出了越來越高的要求。
It was indicated that the real accuracy of velocity field by GPS or VLBI reached 1 mm/a,and SLR 2 mm/a.
SLR實測台站地心速度已經達到2 mm/a的精度。
As shown by images from VLBI, HST, Chandra etc. , the jets are highly relativistic and collimated.
從VLBI、HST和Chandra等觀測設備拍到的圖像中，我們可以推測噴流是以相對論速度運動的，竝可看出它們有很高的準直性。
