Abstract

Until the recent there was no formula enabling to compute the menu square errors for each observed direction for angular measurements in 1st and 2nd order triangulation. It is usually supposed that adjusted values of these directions are equal to the average value calculated from m round. In this paper, there was a deduction of formula enabling to compute the mean square error for each adjusted direction at the reference points. This formula is recommended for the practical use.
