We process the CGPS data, with IGS precise (final) orbit, using BPE (Bernese Processing Engine) . The daily solutions of station coordinates are constrained to seven remote NGS CORS sites (ALBH, DRAO, GOLD, MDO1, NLIB, PIE1, QUIN) in an ITRF2000 reference frame.

To get the time series (residual plot) of each site, we use the Helmert transformation to translate and rotate the coordinates of seven remote NGS CORS sites onto a stable North American reference frame.

Sites with * include time series from the MIT GPS Analysis Center of EarthScope PBO that processes GPS data (later than 2004) from the PBO network, Nucleus network, and selected other stations.
