连续运行参考站实时动态测量技术在带状线路测量中应用

CORS RTK Applications in the Band Line Survey

通过在30 km长的带状线路上按5 km1、km0、.5 km和0.1 km的间距对中线点进行采样,分别比较各相邻点之间的连续运行参考站实时动态测量技术(CORS RTK)高差与水准高差之间的差异,得出在采样点间距不大于1 km时,该带状区域可以用相邻点之间的连续运行参考站(CORS)高差代替水准高差,结果可满足1:2000地形图测绘的高程精度需求,从而对于加快工程进度,缩短工期等具有较强的参考作用。

This article carries on the sampling to the median line spot according to 5 km, 1 kin, 0. 5 km and the 0. 1 km spacing through on the 30 km long belt-shaped line, and separately compares the difference between the CORS RTK elevation difference and the leveling elevation difference of various neighboring points, when the sampling point spacing is not more than 1 kin, it may use the CORS elevation difference to replace the leveling elevation difference of the neighboring points, to satisfy the elevation precision demand of 1：2000 topographic map survey, thus it has the strong practical significance of speeding up the progress of works, reducing the time and so on.
