Wet tropospheric correction for satellite altimetry using SIRGAS-CON products [PDF]
Journal of Geodetic Science, 2022 The wet tropospheric correction (WTC) is a required correction to satellite altimetry measurements, mainly due to the atmospheric water vapor delay. On-board microwave radiometers (MWR) provide information for WTC estimation but fail in coastal zones and

Quality control of SIRGAS ZTD products [PDF]
Journal of Geodetic Science, 2022 The SIRGAS-CON network currently has more than 450 continuous GNSS stations, and it is used for geodetic purposes. In atmospheric studies, it is used for ionospheric monitoring and for the estimation of zenith tropospheric delays (ZTDs). From the Neutral

Assessment of SIRGAS-CON tropospheric products using ERA5 and IGS
Journal of Geodetic Science, 2022 Zenith Tropospheric Delays (ZTDs) are used to correct tropospheric effects that cause a delay in the signal measured by Global Navigation Satellite Systems (GNSS) receivers and obtain accurate measurements.

Strains arising by seismic events in the SIRGAS-CON network region
Journal of Geodetic Science, 2013 In this study, we investigate surface strains related to seismic events and their relationship with pre- and post-seismic events in Latin America, by analyzing the variation of estimated earth coordinates supplied by a geodetic network called SIRGAS-CON.

A Terrestrial Reference Frame (TRF), coordinates and velocities for South American stations: contributions to Central Andes geodynamics [PDF]
Advances in Geosciences, 2009 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 ...
