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.

Few examples of GNSS Monuments
types
–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.
Softwares for data management
and storage
– 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)

• Data from all Brazilian
real time stations are
also collect at the
Master station of
GNSS-SP network.
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;
Applications and services in development
• RTK Network (VRS Concept - Commercial)
Applications and services in development
• RTK Network (I95 Index – among others products)

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.
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.
