利用GPS RTK测定建筑物墙角点方法研究

Research on method of surveying building corner using GPS-RTK

利用GPS RTK方法测定建筑物墙角点坐标时,由于建筑物的遮挡,很难获得点位的固定解。介绍了一种基于GPS-RTK测定建筑物垂直墙角点坐标的新方法,即垂直外伸法。通过实地采样,借助建立的计算公式,对测定结果进行计算改化及比较,证明该方法测定结果的精度可以满足相应规范的要求,具有一定实用性。

It is difficult to measure the fixed value of the coordinates of building corner position of building with obstruction using GPS-RTK method. This paper introduces a new method of measuring the coordinates of building corner based on GPS-RTK,Vertical Extension. The buiding corner coordinates surveyed by GPS-RTK are compared with that by Total Station. The difference is analysed. The result shows that with Vertical Extensive method, the precision of building corner coordinates can meet the requirement of surveying criterion.
