After the successful first full reprocessing of the International GNSS Service (IGS), the Analysis Centers (ACs) of the IGS started the second reprocessing in 2010. The complete history of GPS data collected by the global IGS network since 1994 was consistently reprocessed. This was done using the current models and methods: reference frame IGb08 based on ITRF2008 and using antenna calibrations (igs08.atx), albedo model, geopotential model IERS2010, the a-priori meteorological model GPT2 and the VMF mapping function as well as consideration of higher-order ionospheric effects.

Two GFZ ACs contributed to the first and second IGS reprocessing campaigns. These are the IGS AC (GFZ), which also operates routinely, and the IGS Tide Gauge Benchmark Monitoring Project (TIGA). For the GFZ/TIGA reprocessing, the GPS data of the global IGS and TIGA networks with several hundred stations were reprocessed from 1994 to 2013 and 2015, respectively. The reprocessing solutions contributed to the ITRF2014 with a long and consistent series of station coordinates, GPS satellite orbits, and Earth rotation parameters.
