Results of the SIRGAS 95 GPS Network Processing at DGFI/I

1998
For establishing an accurate and geocentric reference system for South America, Sistema de Referencia Geocentrico para America del Sur (SIRGAS), a continental GPS campaign including more than 60 stations has been carried out in May/June 1995. DGFI/I was acting as one of the analysis centers processing the entire data set.

Toward a SIRGAS Service for Mapping the Ionosphere’s Electron Density Distribution

2011
SIRGAS is responsible of the terrestrial reference frame of Latin America and the Caribbean. To fulfil this commitment it manages a continuously operational GNSS network with more than 200 receivers. Although that network was not planed for ionospheric studies, SIRGAS attempted to exploit it by establishing, in early 2008, a regular service for ...

Report on the SIRGAS-CON Combined Solution, by IBGE Analysis Center

2011
Since the last SIRGAS meeting in May, 2008, IBGE has been playing a role as Processing and Combination Center of SIRGAS-CON network, in order to provide support to the SIRGAS reference frame. The SIRGAS-CON densification network is composed now by 150 continuously operating GNSS permanent stations and this number is increasing continuously. In the same

The Vertical Reference Frame for the Americas — The Sirgas 2000 GPS Campaign —

2002
After the excellent results obtained in the establishment of the South American geocentric reference system (SIRGAS) in 1995, which serves mainly for the unification of the national horizontal datums, there was the need of installing also a unified vertical datum. SIRGAS Working Group III was created for this purpose in 1997. The main objectives are to
