This article analyzes variations in coordinates and uncertainties of GPS networks. Variations occurred when adjustments were performed with different baselines configurations: only independent baselines or all baselines (trivial and independent). Experiments used data from the Brazilian Continuous Monitoring
Network (RBMC) and from static positioning stations mounted during an hydrographic survey performed by the Brazilian Navy Directorate of Hydrography and Navigation (DHN). Several stations and networks configurations were built with data collected in Florianopolis, SC, Brazil, during the last trimester of 2007. Results showed that vertexes coordinates are not altered when adjustment procedures are changed. On the other hand, vertexes uncertainties are more coherent if using all baselines solution.
