DG9810.Formal positional accuracy estimates are not available for this CORS
DG9810.because its coordinates were determined in part using modeled
DG9810.velocities. Approximate one-sigma accuracies for latitude, longitude,
DG9810.and ellipsoid height can be obtained from the short-term time series.
DG9810.Additional information regarding modeled velocities is available on
DG9810.the CORS Coordinates for MYCS2 web page:
DG9810.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DG9810
DG9810.The coordinates were established by GPS observations
DG9810.and adjusted by the National Geodetic Survey in April 2005.
DG9810
DG9810.The datum tag of NAD 83(CORS) is equivalent to NAD 83(CORS96).
DG9810
DG9810.The coordinates are valid at the epoch date displayed above
DG9810.which is a decimal equivalence of Year/Month/Day.
DG9810
DG9810.Due to the release of the International GNSS Service (IGS) 2014
DG9810.realization of the International Terrestrial Reference Frame of 2014
DG9810.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9810.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9810.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9810.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9810.currently published epoch of 2010.00.

DG9810.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9810
DG9810.The ellipsoidal height was determined by GPS observations
DG9810.and is referenced to NAD 83.
