To the issue of balancing networks of trilateration

Results of balansing of two unfree networks trilateration by two variants are given. In one the conditional equations of rigidity are composed as the equations directional angles and coordinates, and in the other variant the conditional equations of coordinates are replaced by the conditional equations of the sums of angles. The experiment allows to assert, that both variants of an balansing are equivalent. But at the second variantthe process of drawing up of the conditional equations of more simple.
