Abstract

Cooperating as part of South American Geocentric Reference System (SIRGAS), whose purpose is to establish a geocentric reference system for the whole of South America, Brazil will take the next step to continue this change.

The integration of Brazilian Geodetic Network to SIRGAS will be carried out through a simultaneous adjustment of the network using the original data and the software Geodetic Adjustment using Helmert Blocking of Space and Terrestrial data (GHOST). In the adjustment will be adopted the GRS80 elipsoid and the Horizontal Network will be constrained to fit the coordinate values of the eleven SIRGAS stations in the national area.

The installation and operation of Brazilian Network for Continuous Monitoring of GPS (RBMC), concluded in 1997, will provide a continuous link to SIRGAS for future users.
