IGb08 Core Reference Frame sites


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.

For more details on the IGb08 core network, see IGSMails 63546663, and this article. A machine-readable list of the IGb08 core stations' 4-character ID is available here
