AI5651.Formal positional accuracy estimates are not available for this CORS
AI5651.because its coordinates were determined in part using modeled
AI5651.velocities. Approximate one-sigma accuracies for latitude, longitude,
AI5651.and ellipsoid height can be obtained from the short-term time series.
AI5651.Additional information regarding modeled velocities is available on
AI5651.the CORS Coordinates for MYCS2 web page:
AI5651.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
AI5651
AI5651.The coordinates were established by GPS observations
AI5651.and adjusted by the National Geodetic Survey in June 2019.

AI5651.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI5651.been affixed to the stable North American Tectonic Plate.
AI5651
AI5651.The coordinates are valid at the epoch date displayed above
AI5651.which is a decimal equivalence of Year/Month/Day.
AI5651
AI5651.Due to the release of the International GNSS Service (IGS) 2014
AI5651.realization of the International Terrestrial Reference Frame of 2014
AI5651.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI5651.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI5651.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI5651.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI5651.currently published epoch of 2010.00.

AI5651.The XYZ, and position/ellipsoidal ht. are equivalent.
AI5651
AI5651.The ellipsoidal height was determined by GPS observations
AI5651.and is referenced to NAD 83.
