前方交会法在净空区障碍物测量中的应用及精度分析

论文主要分析了以GPS、全站仪为主要测量仪器,应用前方交会法进行障碍物测量的过程。在分析障碍物平面测量精度的基础上,提出了交会角不小于3度的要求,最后验证了三角高程测量的精度,为GPS联合全站仪在净空区障碍物测量中的应用提供了科学的依据。

Application of Forward Intersection in Obstruction Survey and Precision Analysis

Based on the precision request of Code for Military Airfield Reconnaissance for obstruction survey,the paper analyses the process that applying the forward intersection in obstruction survey with GPS and total station.After that,through analysis the precision of the horizontal survey,the paper put forward the index that intersection angel is not less than 3 degree.At last,the precision of trigonometric leveling in obstruction survey is verified.All the paper's work is an important for using GPS and total station in obstruction survey.
