Testing of the relative precision in local network with use of the Trimble Geo XR GNSS receivers

The paper deal with testing of different GNSS measurement methods in highly accurate network for the objectives engineering surveying. The test is comprised of a set of measurement acquired by particular GNSS methods with different observation length. For purposes of the test, an appropriate network of five points in local system was created and accurately trigonometrically measured. The result of testing is a comparison of individual methods in position using two dimensional congruent transformation and in height using one dimensional congruent transformation.
