This diploma thesis presents and discusses the results obtained by processing GNSS observations using different software and positioning methods. We performed a GNSS static measurement at six points at the selected site and subsequently processed the observations. The position was determined relatively and absolutely. Namely, the relative position was determined through radial measurement and the offset of the GNSS baseline network using the Leica Infinity, Leica Geo Office and RTKlib software packages and the Trimble Online Processing web application. In order to determine the absolute position, we used the Trimble RTX web application and RTKlib. We compared the differences in the coordinates obtained using various types of processing and established that the results slightly differ, but only by a centimetre level.
