Since the beginning of 2000, the Geodetic Survey Division (GSD) of Natural Resources Canada (NRCan) has been playing a leading role in the North American Reference Frame (NAREF) Working Group of the IAG Commision X Subcommission for North America in support of the International GPS Service (IGS) initiative to densify the International Terrestrial Reference Frame (ITRC) in North America. Following the IGS distributed processing approach, NRCan has been computing three weekly regional solutions for Canada following IGS guidelines. Two such solutions are now being generated by GSD on regular basis for redundancy and quality control, one for a 27 station network using GIPSY-OASIS II software and the other for a 65 station network using the BERNESE GPS Software.
