大气折光对水平角测量影响及对策研究

Influence of Atmosphere Refraction on Horizontal Angle Surveying and Countermeasures

  • 摘要: 通过测量实践和试验,分析了大气折光对特高精度边角测量的影响,指出旁折光是水平角测量误差的主要来源,而对边长的影响甚微;同时,边角网中水平角测量时起始方向的选择十分重要,提出了采用测量机器人作自动观测的一种起始方向确定和质量检查方法;并阐述了特高精度边角网布设和施测中为减少大气折光影响的一些对策。

     

    Abstract: Choosing oriented direction is crucial to line-angle surveying in line-angle nets is put forward in the paper,and how to select the oriented direction as surveying the angles and the means to check the quality of auto-surveying with Georobot are brought forward as well.At last,it expounds some countermeasures to reduce the influence of side-refraction when dispose and survey ultrahigh-precision line angle nets.
