AB: Since 1996 the German Geodetic Research Institute (DGFI) acts as the Regional Network Associate Analysis Centre for the Geocentric Reference System of the Americas (SIRGAS) within the International GNSS Service (IGS RNAAC SIR). It is processing all permanent GPS stations (IGS and regional stations) of South America, Central America, the Caribbean and surrounding areas. Each week a coordinate solution is delivered to the IGS data centres. After the decision of the IGS to introduce the new ITRF2005 (IGS05) and the implementation of absolute phase centre variations since GPS week 1400 the IGS RNAAC SIR at DGFI will reprocess all weekly solutions since GPS week 1860 (July 1996). A new position and velocity solution of IGS RNAAC SIR will be presented containing all reprocessed weeks so far. This paper reports about the station network, the used input data, and the strategy of processing. Comparisons with the latest ITRF2005 solution will be shown (coordinates and velocities). Some remarks will be given on future plans of IGS RNAAC SIR.
