ABSTRACT

The advantage of global navigation satellite systems (GNSS) over other terrestrial
technologies is that it is not affected by uncertainties in the ground layers of the
atmosphere. At present, manufacturers characterize the accuracy of vectors measured by
the static method of GNSS technology using values 5 mm + 1 mm. But also exist
different methods of choice the cofactors of measured quantities by GNSS. The paper
presents experimental measurement of the 3D geodetic network using the technology of
the GNSS, processing and analysis of measurements. Observations were carried out in
July 2009. The aim of the paper is to assess parameters used in the model to estimate
parameters of the first and second order of the network structures.
