The purpose of the article is research and development of approaches and methods that will improve the accuracy of determining the coordinates of objects in the “MAPA” hardware and software complex. This work is aimed at improving the quality and accuracy of geospatial information, which is of great importance for various spheres of activity, including the Armed Forces, cartography, and navigation. The specific goals of the article include: 1. Analysis of the existing methods for determining coordinates and elevations of objects in the “MAPA” hardware and software complex and identifying their limitations. 2. Development and presentation of recommendations that will take into account the elevations of terrain points to improve the accuracy of geospatial determination of coordinates and elevations. 3. Conducting experimental research and testing. This article will contribute to the further development of geospatial technologies and simplify work in areas where the accuracy of coordinates and elevation are critical parameters. Method. Research based on the analysis of available literary sources by this topic, had conducted an overview of scientific works, publications and technological solutions related to the determination of coordinates and elevations of objects. The existing methods of determining coordinates and elevations in the “MAPA” hardware and software complex had compared and analyzed. In the article had experimental studied of the influence of elevations on the determination of coordinates in the “MAPA” software. It had compared of the obtained results with the reference data, the accuracy and features of the research had taken into account. A statistical analysis of the results of the experiments had done for accuracy and reliability assessment. The results. It was found that the existing methods of determining the coordinates of objects in the software and hardware complex “MAPA” have certain limitations, especially with regard to the accuracy of determining the coordinates on the map image. It indicates the demanding to improve the accuracy and reliability of determining the coordinates by this method. The accuracy of the height reference of “MAPY” cartographic materials had studied. A number of experiments had conducted on the test areas using the new method and its results had compared with the values obtained using existing methods from the coordinate catalog. The experiments showed deviations in the accuracy of determining coordinates using a cartographic image. Taking into account the research results in the “MAPA” hardware and software complex can increase the accuracy and reliability of measurements. This study can be used in fields where the accuracy of determining coordinates and heights are critical, in particular the military tasks. Possible areas of further research have been identified, including the expansion of the method to take into account other factors that affect the accuracy of determining the coordinates, and the further upgrade of the “MAPA” hardware and software complex. The scientific novelty consists in the development and implementation of new geodetic data processing algorithms: The article considers modern methods of geodetic data processing, including error correction algorithms, data integration from various sources, as well as the development of methods to ensure higher accuracy of coordinate reference in the “MAPA” software and hardware complex. These algorithms contribute to increasing the accuracy of cartographic support and expanding the possibilities of its use for the military tasks. The article is devoted to the control of the accuracy of cartographic support in the software and hardware complex “Map”. This includes the introduction of analysis of statistical parameters of accuracy, identification of systematic and non -random errors, and development of methods of correction of random deviations. An innovative approach to solving the problem of accuracy: The article emphasizes the innovative approach to solving the problem of accuracy of cartographic support, which is based on the combination of modern technologies, theories of errors and expert experience. Practical meaning. Based on the analysis of the standard deviation using navigation equipment and comparison with the catalog of coordinates of geodetic points, recommendations have been developed for use by commanders of tactical units. The The features of the use of navigation equipment and the necessary consideration of the cartographic image had determined. The conditions which is most appropriate to apply this equipment to topogeodetic survey had studied. The results of the study are designed for unit commanders, who can use it to more effectively perform combat tasks.
