The IGS RNAAC SIR (IGS Regional Network Associate Analysis Centre for SIRGAS) under the responsibility of DGFI-TUM (Deutsches Geodätisches Forschungsinstitut, Technische Universität München) released recently a new multi-year solution for the SIRGAS reference frame. This solution, called SIR15P01, was computed using GNSS (GPS+GLONASS) observations gained after the strong earthquakes occurred in 2010 in Chile and Mexico. It covers a five years period from 2010-03-14 to 2015-04-11. SIR15P01 includes positions and velocities of 303 SIRGAS reference stations and 153 additional stations, which are considered to improve the station distribution towards a post-seismic surface velocity model. SIR15P01 refers to the IGb08 frame, epoch 2013.0. The averaged RMS precision for the station positions at the reference epoch is ±0.7 mm in the north-south component, ±0.9 mm in the east-west component, and ±3.5 mm in the height. The averaged RMS precision for the station velocities is ±0.5 mm/a in the north-south component, ±0.8 mm/a in the east-west component, and ±1.6 mm/a in the vertical component. Results are available at https://doi.pangaea.de/10.1594/PANGAEA.863132.
