Field studies of electronic total stations in a special reference satellite geodetic basis

Abstract

This article presents the results of the conducted field research of two electronic total station, included in the park of geodetic devices performing geodetic work. The article is written on the materials of research work that the authors carried out in the Samarkand region of the Bulungur reference satellite geodetic test site. Electronic total stations, along with receivers for Global Navigation Satellite Systems (GNSS), are now among the most popular tools for surveying and geodesy. One of the important requirements of users to these geodetic instruments is the accuracy of their measurements, on which the accuracy of the surveying and geodesy work performed depends. The studies were carried out on a specialized reference geodetic network, approved for such tests, which is a reference tool for metrological certification of geodetic instruments.

Analysis of the quality of measurements of permanent base stations (UZPOS) in the territory of Samarkand

“…In the area of field research, 3 points of the class 2 triangulation network, the state geodetic network, were selected to study the accuracy of measurements. The error of these definitions is that they do not take into account the time and geometric factors of satellite communication [5].…”

“…Measurement data at permanently operating stations of the CORS network are available on the Internet. In Japan, out of 130 thousand geodetic points that implement the state reference system, more than a thousand are permanent base stations [5].…”

“…One of the points is located as close as possible to one of the UZPOS stations, and also one of them is as far away as possible in the Samarkand region of the Republic of Uzbekistan. The location of the three triangulation points is shown in Figure 3 [5].…”
