This research paper presents a methodology for densification of conventional geodetic
networks by adding GPS points. The feature of this method is to introduce a statistically optimal
procedure, based on least squares principle, that allows adjusting the new points, linking it to
primary points and connecting it to tie-points with same level neighbor points. The main question
to be answered in the current study is how to optimally add stations to the whole geodetic network
(existing and added stations)? Basic formulations are given. A numerical example is presented.
The obtained results are discussed and analyzed. The standard deviations will be used as a
precision criteria.
