The issue of processing GNSS measurements performed to add a new item into a "hard" network is discussed. Two variants of this add: «beam» and «network» are compared. A fragment of the satellite network, which includes five "hard" points of the main network and one defined, acted as the object on which the computational experiment was carried out, testing the theory of this question. The processing of observational materials is implemented in to Excel electronic computational table using an algorithm synthesized version of the parametric version of LS-optimization of spatial data. The «insert» coordinates obtained as a result of this processing and their average square errors were identical for both variants, which is what follows from the theory of LS-optimization of measurement results taking into account of the errors of the coordinates of «hard» points.
