AJ7838.Formal positional accuracy estimates are not available for this CORS
AJ7838.because its coordinates were determined in part using modeled
AJ7838.velocities. Approximate one-sigma accuracies for latitude, longitude,
AJ7838.and ellipsoid height can be obtained from the short-term time series.
AJ7838.Additional information regarding modeled velocities is available on
AJ7838.the CORS Coordinates for MYCS2 web page:
AJ7838.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
AJ7838
AJ7838.The coordinates were established by GPS observations
AJ7838.and adjusted by the National Geodetic Survey in June 2019.
AJ7838
AJ7838.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ7838.been affixed to the stable North American Tectonic Plate.
AJ7838
AJ7838.The coordinates are valid at the epoch date displayed above
AJ7838.which is a decimal equivalence of Year/Month/Day.
AJ7838
AJ7838.Due to the release of the International GNSS Service (IGS) 2014
AJ7838.realization of the International Terrestrial Reference Frame of 2014
AJ7838.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ7838.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ7838.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ7838.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ7838.currently published epoch of 2010.00.

AJ7838.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ7838
AJ7838.The ellipsoidal height was determined by GPS observations
AJ7838.and is referenced to NAD 83.
