Reference Frame Working Group (RFWG)

Brief description
The IGS Reference Frame Coordinator forms the IGS station position and velocity products, and earth rotation parameters, by combining the IGS Analysis Centers' SINEX solutions. Solutions of the GNAACs (see below) contribute quality control to the process. The RFWG also selects and maintains the list of stations whose positions and velocities are included in the IGS realization of the International Terrestrial Reference Frame (ITRF).

Product Coordinator and Working Group Chair
Remi Ferland of Natural Resources Canada's Geodetic Survey Division

IGS Products
IGS cumulative and weekly Reference Frame products, IGS Earth Rotation Parameters (ERP) and geocenter estimates aligned to the IGS realization of ITRF. See the position and velocity products in the product table for detailed characteristics and points of access.
