2 GNSS-SP Network São Paulo State GNSS Network (GNSS-SP); Financial support provide by FAPESP, the Foundation for Research at São Paulo State; Besides GNSS receivers, few stations is also equipped with PTU (Meteorological) devices (Vaisala); Data are sampled every 1 second.

10 Softwares for data management and storage VRS3Net Trimble / RTK Network Spider - Leica: Several scripts for downloads and transfers were developed; NTRIP Caster since 2006; Storage capability of the order of 20?? TB.

11 Data Acess Hourly (1s) and daily (15 s) files in Hatanaka format; Data are mainly used for research, but also made available for practical use (Geodesy and Mapping) Data was provided to the NASA L2CTest net (ROSA, OURI e SJRP) Real time via NTRIP Client (after registering): Several tests being carried out (BKG, Real time PPP, MagicSBAS, IGSRT, JPLRT, LaPlata and FCT/UNESP Ionosphere models)

13 Data from all Brazilian real time stations are also collect at the Master station of GNSS-SP network. NTRIP

14 Applications and services in development GPS Meteorology; Near real time estimation of zenithal tropospheric delays for all Brazilian GNSS Real time stations (GOA-II); These data are made available to CPTEC/INPE NWM (numerical weather model); Several stations equipped with Met devices IWV is computed Near real time TEC computed also from the all Brazilian GNSS Real time stations It is under development Pos processing VRS, RTK and DGPS network;

15 Applications and services in development RTK Network (VRS Concept - Commercial)

21 Future developments From Research and Development to Operational via IGC; IGC is the Institute of Geography and Cartography of São Paulo State IGC has already a license of VRS3Net software and will probably be responsible by the operational duties of the network after the end of the GNSS-SP project. Integration GNSS-SP & CIGALA/CALIBRA Performance of RTK & PPP under IS.

22 Final Considerations Active GNSS network provides several kind of applications, besides the original aim (Geodesy and Cartography); It is a reality with GNSS network of São Paulo State Provides integration of research all over the word (It is already a reality in South America SIRGAS-CON). GNSS Active network of São Paulo State is one of the densest in the South Hemisphere, providing possibility for several kind of research and applications.
