DE6431.Formal positional accuracy estimates are not available for this CORS
DE6431.because its coordinates were determined in part using modeled
DE6431.velocities. Approximate one-sigma accuracies for latitude, longitude,
DE6431.and ellipsoid height can be obtained from the short-term time series.
DE6431.Additional information regarding modeled velocities is available on
DE6431.the CORS Coordinates for MYCS2 web page:
DE6431.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DE6431
DE6431.The coordinates were established by GPS observations
DE6431.and adjusted by the National Geodetic Survey in June 2019.

DE6431.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DE6431.been affixed to the stable North American Tectonic Plate.
DE6431
DE6431.The coordinates are valid at the epoch date displayed above
DE6431.which is a decimal equivalence of Year/Month/Day.
DE6431
DE6431.Due to the release of the International GNSS Service (IGS) 2014
DE6431.realization of the International Terrestrial Reference Frame of 2014
DE6431.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DE6431.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DE6431.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DE6431.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DE6431.currently published epoch of 2010.00.

DE6431.The XYZ, and position/ellipsoidal ht. are equivalent.
DE6431
DE6431.The ellipsoidal height was determined by GPS observations
DE6431.and is referenced to NAD 83.
