Original Abstract

The paper deals with testing of Topcon GRS-1 instrument, specifically with evaluating of the position and height of a point in the good horizon, i.e. better than 75%. The GRS-1 device is GNSS receiver, which is especially designed for GIS applications that are usually associated with single frequency code measurements using an internal antenna. In this case, we expect dm accuracy associated with the method of DGNSS. Nevertheless, the use of this device is wider, because we can use an external antenna for determining the spatial position and use dual-frequency phase RTK measurements with cm accuracy. RTK method may be associated with the use of networks of permanent reference stations. The article describes the preparation for testing in the form of reconnaissance and selection 10 points for measurement. Then it evaluates the testing method of RTK, in which the services of a Czepos network of permanent stations (RTK, MAX, RTK-PRS) and the services of a TopNET network (RTK, VRS-NVR3) have been used. The test results in this paper are interpreted using the graphs for some selected points, and also the tables with the average results of measurement for each service. Then there is the expected accuracy declared by the manufacturer that is compared with the obtained precision by testing and comparing the accuracy of services of a Czepos network.
