摘要
GPS已经被广泛地运用并已发展成为一个真正的三维测量工具,然而测高问题仍然是GPS领域亟待研究解决的问题。就长距离超高压送电线路工程的GPS测量中如何选择大地水准面模型,如何确定GPS测量的高程等问题进行了讨论。
GPS is widely used, and it has been developed to turn into a really three-dimension survey tool. But normal height determination is a urgently problem to be settled. This paper has discussed how to select geoidal model and how to determine normal height in GPS survey of long distance transmission line project.
