precise leveling

基本解釋

To improve the precision of vertical axis of large precise cinetheodolite, a high stiffness base and a deformable leveling mechanism are adopted.
為提高大型精密電影經(jīng)緯儀的垂直軸系精度，采用高剛度底座和可變形調(diào)平機構(gòu)。
To determine the relative positions of them, the GPS technique, traditional direction and range survey, and precise leveling are adopted in this paper.
本文采用GPS技術(shù)及常規(guī)的方向、距離和精密水準測量對三個站進行了空間歸心測量。
Theoretic study and experiment show that the new method solves the problem which simplex GPS leveling can't connect different height systems and so it is an effectively precise method.
理論研究和實驗表明，新方法克服了單純GPS水準無法連接不同高程系統(tǒng)的困難，是一種有效的高精度方法。

They can be precise--they could take out a radar installation on a building without leveling the building.
