| Abstract: | Atmospheric refraction is the main factor to affect the precision of the precise EDM trigonometric leveling.Its influence must be reduced by means of adding a correction to the observational result according to the refraction coefficient.This paper introduces a practicable method of calculating atmospheric refraction coefficient-synthesis inversion method.Making use of the results of the direct and reversed EDM trigonometric leveling directly,we can inverse calculate the refraction coefficients which are corresponding to direct and reversed observation. |
