Abstract

For the widely used method of measuring angles in all combinations in triangulation nets, as well as for other methods of angular measurements there is no techniques enabling to find the value of mean square errors for each sight taken separately. For the angular measurements carried out by the method of rounds there was a formulae deduced for the first time, but it revealed to be not too easy to use. 
In this paper, there is a new formula deduced herein, which is much more simple. Moreover, it requires less computations, especially when the number of directions observed is great n > 6–9). For the same directions this formula give very good results comparing with other formulae. Since this formula deduced in this paper is more convenient and simple, it should be preferred in practice.
