基于全站仪的天文观测与DGPS组合测量方法研究

Astronomic Survey of Total Station Combining with DGPS

摘要:

根据天文方位测量原理,结合全站仪高精度的基线测量功能和DGPS位置测量,对海陆工程测量中目标点或线进行精确解算,测量出目标点位置和基准线的方位,进一步拓展全站仪方位测量功能,解决诸如建筑施工、港口建设、航道疏浚、导管架安装、罗经安装及校准等基准方位、位置标定及复测,使不同作业环境下的位置和方位测量、校准更加简捷、快速,满足工程施工的精度要求。

Abstract:

In this paper, the position and azimuth of the aim point and baseline were calculated according to the principle of astronomical azimuth survey and high precise baseline and position survey of total station and DGPS. So we could survey position of aim point and azimuth of baseline, solved azimuth survey function of total station, such as construction, port building, sea-rote dredging up, jacket installation, etc. It made the azimuth and position survey easy, fast, met requirements of accuracy.
