摘要
Abstract
The definition,station distribution,input data,analysis strategy of ITRF2014 and its transformation parameters with ITRF2008 are introduced.Then improvements of ITRF2014 compared with ITRF2008 are analyzed.ITRF2014 is the recent update of International Terrestrial Reference Frame (ITRF),based on completely reprocessed solutions of the four space geodetic techniques (VLBI,SLR,GNSS and DORIS).Compared with ITRF2008,ITRF2014 not only has more observation data and observing stations,but also has improved the handling of non-linear station motions such as periodic signals and Post-Seismic Deformation (PSD),and it provides two new products including PSD model and geocenter motion model.ITRF2014 provides a uniform spatial datum for the research and application of geoscience and other related subjects and a reference for the maintenance and refinement of other terrestrial reference flames.关键词
