Abstract: The object of research in this work are individual branches and processes of metrology, namely algorithms and methods of global positioning, analysis and research of individual processes, and their implementation in the software model to analyze their accuracy. The existing problem is that some methods or devices that produce results based on these methods are not accurate enough or their accuracy is affected by a number of factors that worsen the result. During the work the methods and approaches of the global positioning system were analyzed, such as: precise point positioning, relative positioning of GPS, static and fast static GPS-shooting and Stop-and-go shooting. Approaches were also divided into static and kinematic. Among the methods, the method of precise point positioning was chosen, as the most common and used among ordinary GPS users, for more detailed research and analysis of accuracy. Development methods are based on the means of interaction with open GPS services, and C#, ASP.NET Core, Angular framework, and development environment Visual Studio Code and Visual Studio 2022. In order to implement all the necessary functionality, the subject area was analyzed, the methods of determining metrological accuracy in general and within the system of global positioning as a direct object of work were considered. As a result of the work the analysis and modelling of the subject area was carried out, the methods of the global positioning system and the software system for the analysis of the accuracy of one of the GPS methods were investigated. The analysis results provided by the software help to understand the accuracy of the method and the GPS receivers that use it on different devices.
