The VRSNET is a commercial active geodetic network of reference stations deployed on Polish territory and in neighbouring countries. The paper presents a spatial analysis of locations of VRSNET permanent stations whose antennas and satellite receivers continuously record signals transmitted by Global Navigation Satellite Systems (GNSS). The study focused on delimiting the potential average range of individual stations in Poland. Spatial analyses, including Voronoi/Thiessen diagram (Dirichlet tessellations) and spatial buffers were used in the research. The study evaluated the geometry of the VRSNET network for the Real Time Kinematic (RTK) measurements that use base vectors solely from the analysed stations. Possible development of the VRSNET network through launching new reference stations was elaborated, too. The spatial analyses indicated the localisation and range of areas with an insufficient density of the VRSNET network. The locations of 16 new reference stations have been delimited on Polish territory. The VRSNET network with newly designed stations was reassessed for validation using the Voronoi/Thiessen diagram and spatial buffers. The results were compared with the parameters for the Active Geodetic Network - European Position Determination System (ASG-EUPOS). Improved RTK measurement geometric parameters resulting from the proposed scenario of the VRSNET network development have been demonstrated. Network density can also have a positive impact on the measurement results of the Network Real Time Kinematic (NRTK). [ABSTRACT FROM AUTHOR]
