Determining the Position of GNSS Network Stations based on the Permanent European GNSS EUREF Network (EPN)

Genti Qirjazi

Abstract: Nowadays technological development in the field of Geodesy, as in any other field, has made a radical change. This has led to the creation of new opportunities to further extend the science of geodesy. The creation of the GNSS satellite system has brought a revolution in the methodology of determining the position of different objects in nature, as the methods used in this case are completely different from classical positioning methods. Today the GNSS system can be called a consolidated system, having been used and performed for several decades. With the growth of communication technology and its integration with the GNSS system, positioning (at cm level) is performed in real time. In the measurement process, getting good and consistent accuracy will always be a big challenge. For this reason, there is always a need to create methodology to increase this accuracy and make it stable throughout the measurement territory. The construction of geodetic networks enables us to create a network of known stations (points) covering a designated territory where any measurement based on these known stations will be obtained within the accuracy of the built network. In this article we will show the creation of a geodetic network using the GNSS satellite positioning method. The built network will be a network based on the permanent European GNSS EUREF network (EPN). To determine the position of points in our network, we have followed several stages that begin with the GNSS measurement process, post-processing of baselines for every measured point by connecting to EPN stations and end with the adjustment computations of our network stations. After the completion of these stages, we will determine the final position of network stations which can be used later to support various measurements that can be realized in the created network area.
