The issues related to the use of products generated from Continuously Operating Reference Station (CORS) for precise positioning are the main focus of the study. Geodetic measurements were conducted at a real site, and different types of data provided by commercial CORS networks were compared – Network Real Time Kinematic (Network RTK) via VRS, generated data for subsequent processing (Virtual Rinex), and raw data from a physical station. The current national regulations, as per [1] , were adhered to, and the aim is to expand the methodology for applying a faster and more efficient approach to determining points in geodetic control networks, ensuring high reliability and accuracy through a comparative analysis.
The construction of geodetic control networks (GCN) and working geodetic bases (WGB) is an essential and integral part of designing and constructing any type of infrastructure projects. In geodetic practice, GNSS determinations are most commonly relied upon as a fast and effective method. For almost all applications, the points determined with GNSS are considered without errors, thus realizing the geodetic coordinate system for the project. With the development of technology and the construction of CORS networks, Network RTK has become the most commonly applied method due to the accessible and easy acquisition of the final result (coordinates of the determined points). However, its application often does not lead to reliable results. On the other hand, the Virtual Rinex product is not widely popular among the geodetic community, though it is not inferior in terms of cost-effectiveness. Some studies on its application have been published in [2] , but its application is not embedded in any regulatory document in the Republic of Bulgaria. |
