Abstract
The geocentric reference system for the Americas (SIRGAS) was initially realized for South America only. A GPS campaign in 1995 covered 58 sites. In 2000 these stations were re-observed and the network was extended to North and Central America as well as the Caribbean. The objectives of the project were completed by the establishment of a unified vertical reference system connecting the classical national height systems. The processing of the 2000 observation data was performed by three analysis centres at DGFI and BEK in Munich as well as IBGE in Rio de Janeiro. The Bernese and GIPSY/OASIS software packages were used. The processing and the comparisons with the 1995 coordinates are described.
