Standardization of reference frames is a fundamental issue for comparison and integration of analysis results by different groups. Participants at the Second International Meeting of the Asia‐Pacific Space Geodynamics (APSG) program not only agreed on this point but felt that such standardization could be provided within their own measurement technique panels. APSG has five such panels, covering radio positioning techniques, gravity, synthetic aperture radar (SAR), satellite laser ranging (SLR), and very long baseline interferometry (VLBI). Participants also agreed that they need to establish a reference network, or a network of fixed stations shared among all of the measurement activities, to get position and velocity measurements that can be related from one experiment to another and from one geographic area to another. The lack of such standardization has plagued other programs and made such comparisons very difficult.
