电磁波测距高程导线测量觇板改进技术研究

为了有效的降低电磁波测距高程导线测量(EDM)野外观测中受到的天候影响,提高全天候条件下EDM测量的测量精度和作业效率,在长期的作业实践中,通过对误差源的分析、收集大量的试验数据,对觇板进行了大胆的改进,并成功的运用到实际作业中。检验结果表明,新型觇板有效的提升了垂直角观测精度,且具有使用轻便、利于观测、可夜晚使用的物理特性。

In order to effectively reduce electromagnetic distance measuring height traverse survey(EDM)field observation in the affected by the weather,improve the measurement precision of measurement under the condition of all-weather EDM and efficiency,in the long-term working practice,through the analysis of error sources,collecting a large number of test data,has carried on the bold improvements to sighting board,and successfully applied to the actual operation.The test results show that the new type of sighting plate can effectively improve the accuracy of vertical Angle observation,and has the physical characteristics of light use,favorable for observation,and can be used at night.
