AF9588.Formal positional accuracy estimates are not available for this CORS
AF9588.because its coordinates were determined in part using modeled
AF9588.velocities. Approximate one-sigma accuracies for latitude, longitude,
AF9588.and ellipsoid height can be obtained from the short-term time series.
AF9588.Additional information regarding modeled velocities is available on
AF9588.the CORS Coordinates for MYCS2 web page:
AF9588.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
AF9588
AF9588.The coordinates were established by GPS observations
AF9588.and adjusted by the National Geodetic Survey in June 2019.
AF9588
AF9588.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9588.been affixed to the stable North American Tectonic Plate.
AF9588
AF9588.The coordinates are valid at the epoch date displayed above
AF9588.which is a decimal equivalence of Year/Month/Day.
AF9588
AF9588.Due to the release of the International GNSS Service (IGS) 2014
AF9588.realization of the International Terrestrial Reference Frame of 2014
AF9588.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9588.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9588.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9588.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9588.currently published epoch of 2010.00.

AF9588.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9588
AF9588.The ellipsoidal height was determined by GPS observations
AF9588.and is referenced to NAD 83.
