Yellowstone-Snake-River-Plain GPS Network
(Click station for time series.)

  • 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, MD01, NLIB, PIE1, QUIN) in an ITRF2005 reference frame.
  • To get the time series (residual plot) of each site, we use the Helmert transformation to translate and rotate the station coordinates onto a stable North American reference frame, WUSC. NGS CORS sites onto a stable North American reference frame.
