Practical implementation of the use of GNSS RTK technologies for obtaining topographic and geodetic data

Abstract

This paper analyzes the use of GNSS equipment when conducting topographic surveys. It was revealed that despite the presence of a large number of modern and high-precision GNSS receivers, nowadays, the regulatory and legal framework has established significant restrictions on the use of GNSS equipment when carrying out topographic and geodetic surveys. According to the current legislation, this equipment cannot accurately determine coordinates and heights on the ground. To prove the opposite, a scientific experiment was carried out, as a result of which it was found that modern GNSS receivers can more accurately determine coordinates and heights on the ground than modern total stations and electronic theodolites. Therefore, it is recommended to use the obtained data of the experiment as a basis for making changes to the regulatory framework.
