Achievements and Challenges of SIRGAS

International Association of Geodesy Symposia, 2009
SIRGAS is the geocentric reference system for the Americas. Its definition corresponds to the IERS International Terrestrial Reference System (ITRS) and it is realized by a regional densification of the IERS International Terrestrial Reference Frame (ITRF).

An Overview of the SIRGAS Project

International Association of Geodesy Symposia, 1998
A general description of the South American Geocentric Reference System (SIRGAS) Project is presented. Since its establishment, in October 1993, the two working groups (“Reference System” and “Geocentric Datum”) of the project have carried out the tasks towards defining a new geocentric reference system and an associated Datum for South America.

CPLat: the Pilot Processing Center for SIRGAS in Argentine

International Association of Geodesy Symposia, 2009
Through the first years after the full deployment of the GPS constellation, the number of permanent GPS stations around the world increased significantly. This process rendered the initial structure of IERS and IGS insufficient and by 1996 led to the creation of the Regional Network Associate Analysis Centers (RNAAC).

Improving SIRGAS Ionospheric Model

2012
The IAG Sub-Commission 1.3b, SIRGAS (Sistema de Referencia Geocentrico para las Americas), operates a service for computing regional ionospheric maps based on GNSS observations from its Continuously Operating Network (SIRGAS-CON). The ionospheric model used by SIRGAS (named La Plata Ionopsheric Model, LPIM), has continuously evolved from a “thin layer”

Deformations Control for the Chilean Part of the SIRGAS 2000 Frame

International Association of Geodesy Symposia, 2007
With the adoption of the Geocentric Reference System for the Americas (SIRGAS), the determination of temporal variations and deformations in its frame are a necessary task. These tasks are fundamental in order to maintain the consistency of the frame with respect to the definition of SIRGAS, especially in the Chilean deformation area, where the ...
