Abstract
Since July 1996 DGFI processes all the available data of permanently observing GPS stations in the mainland of South America and in the surrounding areas as an IGS Regional Network Associate Analysis Center for the SIRGAS Reference System (IGS RNAAC SIR). The observation periods of most of the RNAAC stations are now long enough to solve for reliable velocities. DGFI submitted its solution DGFIOOP01 for ITRF2000. Here we present a new computation extended to the observations in early 2001. Emphasis is given to the vertical movements of stations near tide gauges.
