Research on Accurate Calculation Method of Vertical Atmosphere Refraction Angle in Height Surveying by ETS (Electronic Total Station) Based on Spherical Surface
【摘要】 大气竖直折射是影响竖直角观测精度的关键因素之一。大气竖直折射的计算一直是困扰测绘界的难题。为了更加合理地计算大气竖直折射,提出了基于球面的电子全站仪测高大气竖直折射计算方法,给出了基于球面的电子全站仪测高严格计算公式。
【Abstract】 It is one of the key that the vertical angle surveying precision affected by vertical atmosphere refraction.Vertical atmosphere refraction calculation was a difficult problem all along.To calculate the vertical atmosphere refraction rationally,a calculation method of vertical atmosphere refraction angle in height surveying by ETS(Electronic Total Station)based on spherical surface has been put forward.A calculation formula of height surveying by ETS based on spherical surface has been given.
