| Zusammenfassung |
Satellite positioning systems allow the fixing of the location of a point on
the Earth's surface with very good precision and accuracy. To do this,
however, it is necessary to determine the point coordinates taking account
the reference system and the movements that affect them because of tectonic
plate movements. These reference systems are materialized by a significant
number of continuous measurement stations in South America. In SIRGAS
(Sistema de Referencia Geocéntrico para las Américas), there are
four Analysis Centers that process the data collected from satellites of the
Global Navigation Satellite Systems (GNSS), with the primary purpose to
maintain the international terrestrial reference frame through calculation
of the coordinates and velocities of the continuous GNSS stations of the
SIRGAS-CON Network.
In this work, we demonstrate the quality of the solutions from CIMA, one of
the SIRGAS official processing centers operating in Mendoza, Argentina, in
comparison with other South American processing centers. The importance of
precise calculations of coordinates and velocities in a global frame is also
shown. Finally, we give estimations of velocities from stations located
within deformation zones in the Central Andes. |
