摘要
本文根据用 KERN ME5000测边,用 WILD TC2000/T_3同时对向测定天顶距的观测成果,进而所解算出的控制网点间的高差,探讨了对向观测的高差之差与边长的相依关系以及试验成果的精度,为精密EDM三角高程测量的应用提供了可行性依据。
Based on the observational result with side lengths measured by KERN ME5000, the simultaneously reciprocally observed zeniths by WILD TC2000 and T3 and then the solved height difference between the control net points, this paper discussed the depen-dence between the side length with the difference of the reciprocally observed height difference. The precision of the tested results are also discussed.This may serve as the basis for the feasibility of the application of the precise EDM trigonometriclevelling.
