The article deals with the problem of geodetic monitoring of the technical condition of underwater gas pipeline crossings. The theoretical scheme of increasing the accuracy of depth determination is studied in detail. In this paper, the goal is to increase the accuracy of obtaining the depth of the gas pipeline. The accuracy of the planned position for the largest survey scale (1:500) is 0.75 meters and is achieved using satellite equipment, even without the use of a dynamic positioning system, which allows, if necessary, to increase the accuracy of the data obtained by determining the orientation angles of the vessel. Despite the high popularity of this complex, the accuracy of depth measurements does not correspond to regulatory documents, which raises the question of the need to change the method of measurement and data processing, since the performance of work on monitoring the technical condition of gas pipelines is an important and relevant task. In order to control the developed methodology and automate measurement processing, two programs were written in the Python 3.7 programming language in the Spyder environment.
