The article examines the peculiarities in estimating the accuracy of GPS-schemes when creating basic and survey
surveying networks on the ground surface, as well as geodynamic and geomechanical observation stations with the help
of satellite positioning systems. The article introduces the methods of creating the matrix of coefficients of parametric
equations of relation between the measured values – the lengths of base lines, and parameters – the coordinates of the
defined points. The methods are illustrated with an example of the estimation of the accuracy of geodetic quadrangle
with the calculation of inaccuracies of the defined points location relative to the initial points and the inaccuracy of relative
positions of the defined points (the accuracy of the length and the direction angle of the projectable network sides) with
the help of raw-vectors of weighted coefficients. The article reveals the groundlessness of the practically applicable
estimation of the accuracy of GPS-schemes projects by type of vertical control systems accuracy estimation.

Key words: satellite positioning; project of GPS network; parametric equation; weight matrix; covariance matrix; inaccuracies in the location of point.
