GALILEO/Modernized GPS: A New Challenge to Network RTK

Network RTK in local or regional reference networks has been proven as an efficient technology for high accuracy GPS positioning over the last few years. Comparing with single base RTK, the advantage of network RTK is that large portions of ionospheric and geometric errors are removed through network corrections. Hence network solutions increase the reliability and productivity of ambiguity resolution and the positioning accuracy of rovers working in the system.
