This map shows a well-distributed subset of IGS Reference Frame (RF) stations called IGb08 core network. This well-distributed sub-network is recommended for comparison or alignment of global solutions to the IGb08 Reference Frame, in order to mitigate the aliasing of station non-linear motions into transformation parameters (network effect). It is in particular used for the alignment of the IGS weekly combined solutions to IGb08.
