It is known that adjacent, having a common direction, measured angles in the triangulation are statistically dependent values [2, 3]. The correlation coefficient between such angles is minus 0.5. When this equation is adjusted, this dependence is neglected, assuming all the measured angles to be statistically independent, which distorts the adjustment results.
