AF9651.Formal positional accuracy estimates are not available for this CORS
AF9651.because its coordinates were determined in part using modeled
AF9651.velocities. Approximate one-sigma accuracies for latitude, longitude,
AF9651.and ellipsoid height can be obtained from the short-term time series.
AF9651.Additional information regarding modeled velocities is available on
AF9651.the CORS Coordinates for MYCS2 web page:
AF9651.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
AF9651
AF9651.The coordinates were established by GPS observations
AF9651.and adjusted by the National Geodetic Survey in June 2019.
AF9651
AF9651.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9651.been affixed to the stable North American Tectonic Plate.
AF9651
AF9651.The coordinates are valid at the epoch date displayed above
AF9651.which is a decimal equivalence of Year/Month/Day.
AF9651
AF9651.Due to the release of the International GNSS Service (IGS) 2014
AF9651.realization of the International Terrestrial Reference Frame of 2014
AF9651.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9651.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9651.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9651.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9651.currently published epoch of 2010.00.

AF9651.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9651
AF9651.The ellipsoidal height was determined by GPS observations
AF9651.and is referenced to NAD 83.
