“…In 1993, the Argentine Military Geographic Institute (Instituto Geográfico Militar [IGM]), now the Argentine National Geographic Institute (Instituto Geográfico Nacional [IGN]), began a campaign to acquire Global Positioning System (GPS) measurements on ∼120 benchmarks to produce Argentina's first GPS-based geodetic reference frame (RF), the Geodetic Argentine Positions (Posiciones Geodésicas Argentinas [POS-GAR]) RF. This RF, later called POSGAR94, replaced the original national local system (Campo Inchauspe 69) and was based on GPS observations obtained during field campaigns (Lauría et al, 2002) in collaboration with the National Science Foundation-funded Central Andes GPS Project (CAP).…”

Since its creation in 1998, the Argentine Continuous Satellite Monitoring Network (Red Argentina de Monitoreo Satelital Continuo [RAMSAC]) has grown to include more than 100 continuously operating Global Navigation Satellite Systems (GNSS) stations in Argentina. RAMSAC Receiver Independent Exchange Format (RINEX) data and their derived positioning products (e.g., Networked Transport of RTCM via Internet Protocol [NTRIP] streams and time series) have been used in more than 20 peer-reviewed publications studying the inter-, co-, and postseismic geodynamic evolution of the subduction interface between the South America and Nazca plates. Most of this research has focused on the deformation associated with the near-field megathrust earthquake cycle. Nevertheless, many authors have begun to include in their analyses far-field GNSS observations, which in general do not follow the elastic/viscoelastic deformation predicted by current models. We review the contribution of RAMSAC to scientific knowledge of earthquake elastic deformation and associated phenomena. We also describe the future plans for RAMSAC and the societal impact beyond geodetic and geophysical science.

At each point P referring to the vertical datum i, an observation equation like Eq. [2] can be formulated. At those points referring to two neighbouring vertical datums i, i+1 (see Fig. 1), the observation equation takes the form: Eq. [4] Least-squares estimation of the vertical datum parameters Equations [2] and [4] can be solved by a least-squares adjustment. The functional and stochastic models are given by: Eq. [5] Eq. [6] A is the design matrix containing the coefficients of the unknowns in the observation equations; x is the vector of the unknowns; v contains the residuals; l contains the left-hand side elements in Eqs. [2] and [4]; is the expectation operator; C represents the variance-covariance matrices of the input data. The least-squares solution provides estimates for the vertical datum parameters W 0i
