DE6231.Formal positional accuracy estimates are not available for this CORS
DE6231.because its coordinates were determined in part using modeled
DE6231.velocities. Approximate one-sigma accuracies for latitude, longitude,
DE6231.and ellipsoid height can be obtained from the short-term time series.
DE6231.Additional information regarding modeled velocities is available on
DE6231.the CORS Coordinates for MYCS2 web page:
DE6231.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DE6231
DE6231.The coordinates were established by GPS observations
DE6231.and adjusted by the National Geodetic Survey in June 2003.
DE6231
DE6231.The datum tag of NAD 83(CORS) is equivalent to NAD 83(CORS96).
DE6231
DE6231.The coordinates are valid at the epoch date displayed above
DE6231.which is a decimal equivalence of Year/Month/Day.
DE6231
DE6231.Due to the release of the International GNSS Service (IGS) 2014
DE6231.realization of the International Terrestrial Reference Frame of 2014
DE6231.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DE6231.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DE6231.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DE6231.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DE6231.currently published epoch of 2010.00.

DE6231.The XYZ, and position/ellipsoidal ht. are equivalent.
DE6231
DE6231.The ellipsoidal height was determined by GPS observations
DE6231.and is referenced to NAD 83.
