COMPARATIVE ANALYSIS OF MODERN ELECTRONIC GEODESIC DEVICES

Abstract

Modern geodetic equipment is developing very rapidly. There is a growing need for modern surveying instruments with modern electronics. These devices differ not only in model number, but also in fundamentally new technological solutions. The latest software is used in the devices themselves and in the processing of geospatial data. It provides more opportunities to automate the process of creating terrain models and the implementation of non-standard geodetic tasks. Therefore, now characteristic of the development of modern geodetic equipment is not to increase the accuracy of measurements, but to optimize the workflow using these devices. This is achieved through the development of hardware and software of these devices. This work is devoted to the comparative analysis of modern electronic geodetic instruments on the basis of specific instruments: total stations and GNSS receivers. The study uses methods: observation - to get acquainted with modern surveying equipment, comparison - to determine the technical features of modern electronic surveying instruments, analysis - to identify trends in modern electronic surveying instruments, sampling - to select instruments that will characterize their categories. A comparative analysis of modern geodetic instruments on the example of total stations Leica TS09 plus 1 "R500, Leica Nova MS60 1" and GNSS receivers GNSS Leica GS08Plus, Leica GS18 I was carried out to determine trends in modern electronic geodetic instruments. Thus, from this analysis follows a certain pattern. It is that there is no race for the accuracy of instruments - modern instruments have a very high accuracy. There is also a new trend in the technological development of geodetic instruments in the direction of increasing functionality and automation.
