Atmospheric vertical refraction is the main factor affecting the accuracy of the photoelectric triangle’s elevation in the plain area. Based on the experimental results, this paper makes a preliminary qualitative analysis of the effect of atmospheric vertical refraction on the low line-of-sight trigonometric height measurement, and proposes an exploration perspective for the application of low-line-of-view trigonometric elevation.
