ITRF Densification and Continuous Realization by the IGS

The tools and infrastructure are now in place to realize a global, terrestrial, kinematic reference frame with few millimeter precision, which is both spatially dense, and can be reliably updated on a frequent basis (e.g., monthly). A procedure is outlined by which IERS can continuously realize the ITRF using methodology developed by the International GPS Service (IGS). However, spatial densification not only requires such a processing scheme, but also requires the recruitment of interested groups to participate in this venture.
