heal.abstract	Network-based real-time kinematic (NRTK) positioning in local or regional reference networks has been proven to be an efficient technology for high precision global positioning systems (GPS) positioning over the last few years. With a view to GPS modernization and the development of the European Galileo system, considerable improvements are expected, enabling high reliability of real-time kinematic (RTK) rover positioning on distances larger than the typical ones of current RTK networks. This paper evaluates the expected performance of a GPS/Galileo NRTK by assessing the spatial variability of specific quality indicators; namely, the success rates of correct integer ambiguity resolution and the network internal reliability. This approach provides a useful tool for design analysis of RTK networks. The Greek GPS-RTK network is used to simulate different geometric configurations to demonstrate in a practical sense whether or not a particular configuration can meet the user specified requirements. As a result of this study, a priori indication on the network reliability associated with different geometries is obtained, and the limitations of the network as a function of the station geometry can be ascertained. © 2011 American Society of Civil Engineers.	en
